Guardant Health Announces FDA Approval of Guardant360 CDx as Companion Diagnostic for Boehringer Ingelheim’s HERNEXEOS®June 11, 2026 8:05 AM
Business Wire Blood-based liquid biopsy test enables identification of patients eligible for treatment with HERNEXEOS® (zongertinib tablets) Guardant Health, Inc. (Nasdaq: GH), a leading precision oncology company, today announced that the U.S. Food and Drug Administration (FDA) has approved Guardant360® CDx as a companion diagnostic (CDx) for Boehringer Ingelheim’s HERNEXEOS® (zongertinib tablets), the first targeted therapy for adults with HER2 (ERBB2)-mutant advanced non-small cell lung cancer (NSCLC) as an initial treatment option. The approval enables Guardant360 CDx, a liquid biopsy test that analyzes circulating tumor DNA (ctDNA) from a simple blood draw, to identify patients with HER2 (ERBB2) tyrosine kinase domain activating mutations who may be eligible for treatment with HERNEXEOS. HERNEXEOS is indicated for the treatment of adult patients with unresectable or metastatic non-squamous NSCLC whose tumors have HER2 (ERBB2) tyrosine kinase domain activating mutations, as detected by an FDA-authorized test. This indication was approved under accelerated approval based on objective response rate and duration of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial. More information and full prescribing information can be found at HERNEXEOS.com. “This approval highlights the growing impact of liquid biopsy across advanced cancer care and underscores the utility of Guardant360 CDx to ensuring more patients can be matched to the right therapy at the right time,” said Helmy Eltoukhy, Guardant Health chairman and co-CEO. “Guardant360 CDx has been at the forefront of enabling comprehensive genomic profiling through a simple blood draw, helping clinicians identify actionable mutations in genes such as HER2 with speed and accuracy.” Guardant360 CDx was the first FDA-approved liquid biopsy that provides comprehensive genomic profiling across multiple tumor types and biomarkers. By detecting tumor-derived alterations in circulating cell-free DNA, the test helps clinicians match patients to appropriate targeted therapies and clinical trials. “Companion diagnostics are essential to personalized lung cancer care, guiding biomarker-driven treatment decisions,” added Vicky Brown, U.S. Therapeutic Area Head for Oncology and Emerging Areas, Boehringer Ingelheim. “Guardant360 CDx will help identify patients with HER2-mutant advanced non-small cell lung cancer and connect eligible patients to the appropriate targeted therapy when timely treatment decisions matter most.” NSCLC is the most common type of lung cancer, and a subset of patients harbor HER2 mutations that may be targetable with precision therapies. HER2-mutant NSCLC is an aggressive type of lung cancer that has been associated with a poor prognosis. Blood-based testing offers a faster, less invasive alternative to tissue biopsy, which can be challenging in advanced disease. This latest FDA approval for Guardant360 CDx marks the 27th CDx indication across multiple tumor types globally, building on the platform’s increasing clinical utility and broad coverage by Medicare and commercial payers, representing more than 300 million covered lives.

American Cancer Society Recommends Guardant Health’s Shield Blood Test in Updated Colorectal Cancer Screening GuidelinesMay 27, 2026 7:47 AM
Business Wire Updated ACS guideline offers Shield as a new choice for over 50 million eligible Americans who are not up to date with their colorectal cancer screening Shield is the first and only FDA-approved blood test included in both ACS and NCCN guidelines Guardant Health, Inc. (Nasdaq: GH), a leading precision oncology company, announced that its FDA-approved Shield™ blood test is now included in updated American Cancer Society (ACS) Colorectal Cancer (CRC) Screening Guidelines published today. The major screening guideline update recommends Shield as a choice for patients who decline or have not completed stool-based or visual examination screening tests. In an effort to address persistent screening gaps and rising CRC rates in adults under 65, ACS guidelines now recommend Shield blood-based CRC screening as a new option to expand access and screening participation. Shield is the first and only FDA-approved blood test for primary colorectal cancer screening in average-risk adults age 45 and older and can be completed with just a blood draw during a routine doctor’s visit. CRC is the second leading cancer killer in the United States1 and the number one cancer killer for adults under 50.2 The inclusion of Shield in the updated guidelines acknowledges a central challenge in colorectal cancer screening: more than 50 million eligible adults3 remain unscreened despite established methods like colonoscopy or stool-based testing existing for decades. By recognizing the effectiveness of a blood-based option, the updated guidelines add a new opportunity to reach patients who might otherwise go unscreened. With three out of four CRC deaths among those not up to date with screening4, the American Cancer Society noted that “offering multiple, recommended screening options supports informed patient choice and may improve participation, because the most effective screening test is the one that the patient completes.” “The inclusion of Shield in the American Cancer Society’s guidelines as a recommended option is a momentous step forward in our collective work to reach the more than 50 million Americans who remain unscreened for colorectal cancer,” said AmirAli Talasaz, Guardant Health co-CEO. “We know that tragically cancer does not wait. The Shield blood test has been proven to be effective in detecting cancers and increasing screening participation in the real-world setting. By making colorectal cancer screening more accessible with a blood-based option in conjunction with other established methodologies, we can get people screened.” Guardant’s Shield blood test stood out in guideline evidence for having the highest screening adherence rate compared to traditional colonoscopies and stool-based tests.5 In the real-world experience with approximately 200,000 patients tested, Shield is proven to increase screening rates with over 90% of patients completing the test.6 In the pivotal ECLIPSE study, Shield showed its high sensitivity in detecting colorectal cancers and demonstrated sensitivity of 100% in detecting stage II and above cancers.7 “Screening rates have been largely stagnant across the population, with particular challenges in delivering screening to younger individuals age 45 to 55, racial and ethnic minoritized groups, and individuals with lower socioeconomic position. By providing the choice of a new CRC screening modality, blood-based testing has the potential to expand the reach of CRC screening to individuals who might otherwise remain unscreened,” said Samir Gupta, MD, Professor of Medicine at the University of California San Diego. “Today’s guideline update reflects the continued evolution of CRC screening-related technological advances, outlines persistent gaps in screening participation, and the potential for advances like blood-based testing to increase screening uptake.” Demonstrating strong real-world evidence and clinical performance published in the New England Journal of Medicine (NEJM)7, Shield is the only FDA-approved blood test included in both ACS and National Comprehensive Cancer Network (NCCN) guidelines. “The new ACS guidelines recognize that colorectal cancer screening is not one size fits all. Patients have several screening options, and their choices are impacted by where they live, their access to care, financial pressures, personal preferences, and individual risk factors,” said Anjee Davis, MPPA, CEO at Fight Colorectal Cancer. “As options expand, Fight CRC remains committed to patients making an informed choice, providing clear education, and ensuring timely follow up so more people can complete lifesaving screening. Our shared goal is clear: achieving 80% screening rates in every community.” “Presenting patients with options helps them make educated health decisions,” said Chris Evans, President of the Colon Cancer Coalition. “The introduction of a blood-based choice for colorectal cancer screening will increase screening rates and ultimately save lives.” ACS guidelines for colorectal cancer screening were last updated in 2018 to lower the recommended age for screening for adults at average risk from 50 to 45 in response to the rising rate of CRC among younger adults.

Guardant Health Receives FDA Approval for Guardant360® CDx as a Companion Diagnostic for Arvinas and Pfizer’s VEPPANU (vepdegestrant) for Patients with ER+/HER2- Advanced Breast Cancer with ESR1 MutationsMay 4, 2026 8:05 AM
Business Wire

Blood-based test enables identification of patients eligible for targeted treatment with VEPPANU™



Approval marks Guardant’s third ESR1 companion diagnostic FDA approval to help guide timely treatment decisions for patients with advanced breast cancer



Guardant Health, Inc. (Nasdaq: GH), a leading precision oncology company, today announced that the U.S. Food and Drug Administration (FDA) has approved the Guardant360® CDx liquid biopsy test as a companion diagnostic for VEPPANU (vepdegestrant). VEPPANU, jointly developed by Arvinas, Inc. and Pfizer Inc., is approved for the treatment of adults with estrogen receptor-positive (ER+), human epidermal growth factor receptor 2-negative (HER2-), estrogen receptor 1 (ESR1)-mutated advanced or metastatic breast cancer, as detected by an FDA-authorized test, with disease progression following at least one line of endocrine therapy.


The approval of Guardant360 CDx enables a non-invasive, blood-based method to identify patients with ESR1 mutations who may be eligible for treatment with VEPPANU. ESR1 mutations are a known mechanism of resistance to endocrine therapy and are commonly observed in patients with advanced disease.


“This latest FDA approval using Guardant360 CDx reflects where cancer care is headed using blood-based testing to detect resistance earlier and guide smarter treatment decisions,” said Helmy Eltoukhy, Guardant Health chairman and co-CEO. “By identifying ESR1 mutations with just a simple blood draw, we’re helping bring more precise, personalized options to patients when they need them most.”


Vepdegestrant, discovered by Arvinas and co-developed with Pfizer, is a PROteolysis TArgeting Chimera (PROTAC), a type of heterobifunctional protein degrader therapy. It is designed to selectively degrade the estrogen receptor, offering a targeted treatment option for patients whose cancers are driven by ESR1 mutations. The approval is supported by clinical data demonstrating the clinical utility of identifying ESR1 mutations to guide treatment selection in ER+/HER2- advanced breast cancer.


This latest FDA approval for Guardant360 CDx marks the third ESR1 companion diagnostic approval. It is the 26th companion diagnostic indication across multiple tumor types, building on the platform’s increasing clinical utility and broad coverage by Medicare and commercial payers, representing more than 300 million covered lives.

Guardant Health real-world data supports Japan approval of ENHERTU for HER2-positive tumorsMarch 30, 2026 10:29 AM
IH Market News
Guardant Health, Inc. (NASDAQ:GH) said real-world evidence generated through its InfinityAI platform helped support the recent approval of ENHERTU® (trastuzumab deruxtecan) in Japan for patients with previously treated HER2-positive metastatic solid tumors.Japan’s Ministry of Health, Labour and Welfare (MHLW) granted the approval for ENHERTU, which is developed and commercialized by Daiichi Sankyo (TSE:4568), for patients with advanced or recurrent HER2-positive cancers — defined as HER2 (ERBB2) gene amplification or immunohistochemistry (IHC) 3+ — who are refractory or intolerant to standard treatments.The regulatory decision was supported by results from multiple clinical trials, including HERALD, DESTINY-PanTumor02, DESTINY-CRC02 and DESTINY-Lung01, along with supplemental real-world evidence generated using InfinityAI, Guardant Health’s artificial intelligence platform for analyzing clinical and molecular datasets.HER2 amplification is well established in breast cancer, but identifying eligible patients and building evidence in other tumor types remains challenging, particularly in biomarker-defined populations with relatively low prevalence. In these settings, real-world data can help identify patients at scale and better characterize unmet medical need.For the Japanese regulatory submission, Daiichi Sankyo incorporated real-world evidence derived from InfinityAI alongside clinical trial results. Guardant Health and Daiichi Sankyo jointly analyzed outcomes from a large cohort of patients whose HER2 amplifications were identified using Guardant360®, showing significant unmet need and real-world clinical relevance across multiple tumor types.The collaboration demonstrates how large-scale real-world evidence can complement traditional clinical trial data, particularly in genomic subpopulations where enrolling sufficient patients into trials can be difficult.“This approval highlights the growing role of real-world evidence in precision oncology and underscores the potential for new regulatory pathways in rare biomarker-defined populations,” said Helmy Eltoukhy, Guardant Health chairman and co-CEO. “InfinityAI allows us to generate clinically meaningful evidence from large-scale, longitudinal data, helping to complement traditional trials and ultimately expand access to targeted therapies for patients who might otherwise be overlooked.”About InfinityAIInfinityAI is Guardant Health’s artificial intelligence and machine learning platform designed to generate real-world evidence and data-driven insights. The platform is built on a large proprietary dataset derived from Guardant Health’s clinical testing portfolio and integrates longitudinal, multimodal molecular and clinical information, including genomic and epigenomic data, into a unified framework.InfinityAI supports pharmaceutical and healthcare partners across research, drug development and clinical applications such as biomarker discovery, patient identification and clinical trial optimization.

Guardant Health’s InfinityAI Real-World Evidence Supports Approval of ENHERTU® for Previously Treated Patients with HER2-Positive Metastatic Solid Tumors in JapanMarch 30, 2026 8:05 AM
Business Wire

This milestone underscores the power of Guardant Health’s InfinityAI platform and real-world data to enable innovative evidence generation in rare biomarker-defined populations



Guardant Health, Inc. (Nasdaq: GH), a leading precision oncology company, today announced that real-world evidence generated from Guardant’s InfinityAI contributed to the recent approval of ENHERTU® (trastuzumab deruxtecan), developed and commercialized by Daiichi Sankyo (TSE:4568) in Japan, for the treatment of patients with HER2-positive (HER2 [ERBB2] gene amplification or immunohistochemistry [IHC] 3+) advanced or recurrent solid cancers refractory or intolerant to standard treatments. This approval, granted by Japan’s Ministry of Health, Labour and Welfare (MHLW), was supported by data from the HERALD, DESTINY-PanTumor02, DESTINY-CRC02 and DESTINY-Lung01 clinical trials and supplemental real-world evidence (RWE) generated using the real-world data platform from InfinityAI, Guardant Health’s artificial intelligence platform.


HER2 amplification is well characterized in breast cancer but patient identification and evidence continues to be challenging. In biomarker-defined populations with low prevalence, real-world data (RWD) can play a critical role in identifying patients at scale and characterizing unmet need.


To support its MHLW application, Daiichi Sankyo incorporated real-world evidence generated from InfinityAI as supplemental data alongside clinical findings. Together, Guardant Health and Daiichi Sankyo analyzed outcomes from a large cohort of patients with HER2 amplifications detected via Guardant360®, demonstrating significant unmet need and real-world clinical relevance across multiple tumor types.


The collaboration illustrates an innovative pathway that leverages high-quality RWE to complement clinical trial data, particularly in genomic subpopulations where traditional trial enrollment may be limited.


“This approval highlights the growing role of real-world evidence in precision oncology and underscores the potential for new regulatory pathways in rare biomarker-defined populations,” said Helmy Eltoukhy, Guardant Health chairman and co-CEO. “InfinityAI allows us to generate clinically meaningful evidence from large-scale, longitudinal data, helping to complement traditional trials and ultimately expand access to targeted therapies for patients who might otherwise be overlooked.”

Verana Health and Guardant Health Partner to Advance Precision Medicine with Real-World DataMarch 24, 2026 9:15 AM
PR Newswire (US)

Combination of high quality, variable-rich, curated EHR data with genomics enhances understanding of the patient journey and aids in therapy development SAN FRANCISCO, March 24, 2026 /PRNewswire/ -- Verana Health®, a digital health company dedicated to revolutionizing patient care and clinical research through real-world data (RWD), has announced a new partnership with leading precision oncology company Guardant Health Inc. (Nasdaq: GH) that will allow biopharmaceutical researchers to access the combined resources of Verana's regulatory-grade, therapeutic-specific EHR curated datasets from leading medical societies and academic and community medical centers and Guardant's clinicogenomic testing data to accelerate the development of new therapies and enhance on-going patient care.







Using the extensive datasets the collaboration provides, research scientists can more easily understand and further validate correlations between molecular biomarkers, treatment decisions and clinical outcomes. For example, from an urology perspective novel use cases of combining genomics data with NMIBC EHR curated data could enhance understanding the patient journey in risk refinement beyond stage/grade, lead to better treatment selection insights (i.e., who benefits from Bacillus Calmette-Guerin (BCG), the standard of care for most Non-muscle invasive bladder cancer (NMIBC) patients vs. who needs earlier escalation, and validate biomarker measures (e.g., Tumor Mutational Burden (TMB)) using real-world response and outcome endpoints. Ultimately, the combination provides greater insights into existing research data with comprehensive real-world data—including critical longitudinal serial testing information—needed to optimize drug development and accelerate programs that treat cancer across diverse patient populations."Clinicogenomic data empowers research scientists to test hypotheses by studying patient genomic profiles and real-world outcomes to guide the development of targeted therapies that can be used to personalize treatment for each cancer patient," said Sujay Jadhav, CEO of Verana Health. "Connecting Guardant's data to Verana Health's in-depth, real-world oncology, and urology data assets will also allow researchers to anticipate treatment responses and accelerate drug development for existing and new population segments.""The real-world data partnership with Verana marks another significant milestone in our mission to advance novel therapies, in particular cancer, with data," said Craig Eagle, MD, Guardant Health chief medical officer. "Giving biopharmaceutical researchers the ability to connect detailed information about tumor biology and therapy response with real-world patient outcome data will expedite the discovery of new biomarker-based therapies for patients and make the drug development process more economical as well."Guardant's extensive real-world longitudinal serial testing datasets span all stages of the disease, from initial tumor profiling for therapy selection to recurrence and therapy response monitoring, while Verana Health's highly curated data tracks a patient's complete cancer care journey, drawing from both academic and community care center settings. This new collaboration with Guardant deepens Verana Health's data by expanding its breadth into solid tumors, particularly lung, breast, and colorectal cancers, creating a broader, more diverse data set with considerable patient overlap for enhanced clinical insights.The recent merger of COTA with Verana Health has expanded the therapeutic footprint. With its focus on real-world patient data in oncology, COTA complements Verana Health data and technology offerings across ophthalmology, urology, and neurology. The company is an exclusive partner of the American Academy of Ophthalmology IRIS® Registry (Intelligent Research in Sight) and the American Urological Association (AUA) Quality (AQUA)® Registry. The combined portfolio supports life sciences companies with clinical trials, drug submissions, health economics research, market-access strategies, and clinicians with MIPS advisory services.The merger strengthens Verana Health's relationships within the biopharma industry.

Guardant Health, Inc. (Nasdaq: GH), a leading precision oncology company, today announced the company and its research collaborators will present 28 abstracts, including 3 oral sessions, showcasing advances in methylation-based tumor classification and liquid biopsy technology at the American Association for Cancer Research (AACR) Annual Meeting in San Diego, California taking place April 17 - 22, 2026.


Key data that will be presented include:



An oral presentation of research data showing high accuracy of Guardant360 Tissue in determining tissue of origin with strong performance in cancers of unknown primary, correctly identifying the likely origin in approximately 92% of known cases across more than 6,000 tissue samples and 24 tumor types and supporting the clinical utility of methylation-based tumor typing for tissue samples in diagnostically challenging settings.



An oral presentation showcasing the expanded utility of Guardant360 Liquid beyond basic genomic testing, highlighting the strength of its novel epigenomic features in increasing clinical actionability. Researchers found that Guardant360 Liquid demonstrated actionable findings for 85% of metastatic breast cancer patients and 89% of patients with advanced colorectal cancer.



A real-world analysis evaluating the utility of Guardant Reveal to identify new primary malignancies during minimal residual disease (MRD) monitoring, demonstrating the potential to detect separate primary cancers in patients over time with non-invasive, liquid biopsy technology.



Additional research bolstering the potential of Guardant360 Tissue in expanding access to targeted treatment options showing that a tissue-based genomic instability score (GIS) can accurately detect DNA repair deficiencies in breast, ovarian, and pancreatic cancers and accurately identifying patients who may benefit from PARP inhibitors.



“The breadth of the data Guardant will be presenting demonstrate the power of our blood- and tissue-based tests in helping address critical gaps across cancer care,” said Dr. Craig Eagle, Chief Medical Officer at Guardant Health. “From identifying cancers of unknown primary and detecting new malignancies in tandem with MRD monitoring to expanding treatment options for more cancers, we are eager to present these findings along with our research collaborators at the AACR meeting and proud to offer innovative tests that are meeting today’s most complex challenges in cancer care.”

New Guardant Health/Harris Poll Survey Shows 92% of All Eligible Americans Believe Colorectal Cancer Blood Tests Should be Accessible and Covered Similar to MedicareMarch 13, 2026 8:05 AM
Business Wire

Survey highlights barriers to colorectal cancer screening for adults 45 and over



Overwhelming majority (92%) of Americans ages 45 and over believe blood-based screening should be covered with no co-pay



Shield™ by Guardant is proven to increase screening rates with a 93% adherence rate by offering a quick, easy option to screen with just a blood draw



Guardant Health, Inc. (Nasdaq: GH), a leading precision oncology company, today announced the results of a new national survey conducted on its behalf by The Harris Poll with findings demonstrating that more than 9 out of 10 Americans ages 45 and over believe in ensuring broader coverage for blood-based colorectal cancer (CRC) screening, including new innovations like Shield™ by Guardant, a methylation partitioning cell-free DNA (mp-cfDNA) test and the first and only FDA-approved blood test for primary colorectal cancer screening.


The survey showed an overwhelming majority of Americans of screening-eligible age (92%) believe that blood-based colorectal cancer screening should be covered with no co-pay similar to Medicare Part B and VA Community Care coverage. National CRC screening guidelines from the United States Preventive Services Task Force (USPSTF) were last updated in 2021 lowering the recommended screening age from 50 to 45 for average risk individuals, but have yet to be updated to include a new innovative screening option approved by the FDA in 2024.


Poll findings also highlighted the likely barriers to colorectal cancer screening, including colonoscopies and stool-based tests, as millions of Americans ages 45 and over remain unscreened.



A majority (71%) have felt/would feel anxious before having a colonoscopy



Over three-quarters of screening-eligible Americans (77%) said they would be less likely to avoid or delay a colorectal cancer screening knowing that there is an FDA-approved blood test option available



85% of screening-eligible Americans said they would be more likely to get a colonoscopy if they had a positive result on a blood-based colorectal cancer screening test first



Over half (54%) say stool-based tests “gross them out,” and nearly two in five (38%) say they would have a hard time completing one



“This year’s survey conducted by The Harris Poll gives insight into the barriers that drive millions of Americans to avoid their recommended colorectal screening and the overwhelming support in expanding access to the latest innovation in colorectal cancer screening to close our nation’s screening gap,” said Dr. Craig Eagle, M.D. Guardant Health chief medical officer. “Preventive care should be accessible to everyone. Guardant’s Shield blood test is a critical avenue in getting more patients screened by providing a quick, easy option to screen for colorectal cancer with just a blood draw, helping to detect cancer early, when it’s more treatable.”


Colorectal cancer is the second leading cause of cancer-related deaths in the U.S. with a 91 percent five-year survival rate if caught in early stages.1 Shield is proven to increase screening rates in the real world, with 93% of patients completing the test in the first 100,000 Shield tests ordered - a significant improvement in screening adherence rates over other types of tests.2


Recently, the National Comprehensive Cancer Network included the Shield blood test in its updated CRC screening guidelines, paving the way for improved patient access and additional major clinical guideline inclusions. Shield is covered by Medicare, Veterans Affairs Community Care Network and TRICARE, and is commercially available across the U.S.


The Harris Poll conducted the survey on behalf of Guardant Health from February 24-26, 2026, among 1,189 U.S. adults aged 45 and older. Data was weighted where necessary to reflect the U.S. population. The sampling precision of Harris online polls is measured using a Bayesian credible interval. For this study, the sample data are accurate to within ± 3.6 percentage points using a 95% confidence level.


For complete survey methodology, including weighting variables and subgroup sample sizes, please contact Meaghan Smith at Guardant Health.


About Shield


Shield is a methylation partitioning cell-free DNA (mp-cfDNA) non-invasive, blood-based screening test that detects alterations associated with colorectal cancer in the blood. It is intended as a screening test for individuals at average risk for the disease, age 45 or older, and is not intended for individuals at high risk for colorectal cancer. The Shield test can be considered in a manner similar to guideline-recommended non-invasive CRC screening options and can be completed during any healthcare visit. A positive Shield result raises concern for the presence of colorectal cancer or advanced adenoma and the patient should be referred for colonoscopy evaluation.

Guardant Health’s Shield Blood-based Screening Test for Colorectal Cancer Now Accessible Through National Test Ordering and Collection Network of Quest DiagnosticsMarch 10, 2026 8:05 AM
Business Wire

Strategic collaboration to enable streamlined and accelerated access to Shield blood-based colorectal cancer screening test across Quest’s vast network



Physicians nationwide now have the ability to order Shield



Shield is proven to increase screening rates with a 93% screening adherence rate



Guardant Health, Inc. (Nasdaq: GH), a leading precision oncology company, today announced that the Shield™ by Guardant blood-based screening test is now widely accessible for physician order through the nationwide connectivity of Quest Diagnostics, equipping clinicians with access to blood-based screening innovation for colorectal cancer (CRC) through one of the largest diagnostic ecosystems in the United States.


Shield is the first and only blood test to receive full FDA approval as a primary screening option for colorectal cancer in average-risk adults aged 45 and older. Under the agreement, providers that order lab testing from Quest can now directly access Shield through their existing Quest account and electronic health record (EHR).


Quest provides healthcare connectivity solutions to nearly 650,000 clinician and hospital accounts annually in the United States. Providers can also utilize Quest’s approximately 2,000 patient service centers and approximately 6,000 in-office phlebotomists across the United States for blood draws for Shield.


“Activating our strategic collaboration with Quest marks a pivotal milestone in broadening access to Shield and empowering primary care physicians across the country to bring the lifesaving advantages of early detection to their patients with just a blood draw,” said AmirAli Talasaz, Guardant Health co-CEO. “Shield’s innovative technology supported by Quest’s vast, nationwide infrastructure will strengthen our ability to fundamentally transform colorectal cancer screening by equipping doctors with a quick, easier screening option patients are far more likely to complete.”


As part of the strategic arrangement, Quest’s national commercial sales team will actively educate primary care physicians about access to the test.


Colorectal cancer is the second leading cause of cancer-related deaths in the U.S. with a 91 percent five-year survival rate if caught in early stages.1 Yet, over 54 million people do not complete the recommended screening, in part because they find the available options, colonoscopy and stool tests, unpleasant or inconvenient.2 With Shield, individuals can be screened with just a blood draw, helping to detect cancer early, when it is more treatable.


Shield is proven to increase screening rates in the real world, with 93% of patients completing the test in the first 100,000 Shield tests ordered – a significant improvement in screening adherence rates over other types of tests.3 Recently, the National Comprehensive Cancer Network included the Shield blood test in its updated CRC screening guidelines, paving the way for improved patient access and additional major clinical guideline inclusions.

Guardant Health Launches Community Colorectal Cancer Screening Grant Program in Recognition of CRC Awareness Month, Applications Now OpenFebruary 12, 2026 2:35 PM
PR Newswire (US)

Patient and Public Health Groups Invited to Apply for Up to 100 Shield Colorectal Cancer Blood Tests to Support Community Screening Events and Educational Outreach in MarchPALO ALTO, Calif., Feb. 12, 2026 /PRNewswire/ -- Ahead of Colorectal Cancer (CRC) Awareness Month in March, Guardant Health, Inc. (Nasdaq: GH), a leading precision oncology company, today announced the launch of its Community Colorectal Cancer Screening Grant Program, designed to support community-led efforts to expand access to colorectal cancer screening throughout March.As part of the grant program, Guardant Health will provide selected patient advocacy, non-profit, public health and health-adjacent organizations with up to 100 Shield tests per organization to support efforts to increase screening participation, including community health fairs, screening events and awareness month programming and educational outreach. All Shield tests will be provided at no cost to the patient or participating organization.Shield is the first and only blood test approved by the FDA as a primary screening option for CRC for adults age 45 and older at average risk, offering patients a more pleasant and convenient option for screening by overcoming barriers associated with other screening methods.Colorectal cancer is the leading cause of cancer-related deaths nationwide, yet it is highly preventable through recommended screening. Guardant's grant program reflects the company's commitment to removing barriers to screening – particularly in underserved and underscreened communities – and supporting community partners who are on the front lines of improving access to screening. Organizations with strong community and health outreach are encouraged to apply. Groups interested in participating should review the Request for Proposals (RFP) and complete the application form available here. Applications are due by February 17, 2026 (midnight PST), and approval notifications will be sent via e-mail on February 20, 2026.For questions about the application process, contact ShieldGrants@guardanthealth.com.About Shield
Shield is a methylation partitioning cell-free?DNA?(mp-cfDNA) non-invasive, blood-based screening test that detects alterations associated with colorectal cancer in the blood. It is intended as a screening test for individuals at average risk for the disease, age 45 or older, and is not intended for individuals at high risk for colorectal cancer. The Shield test can be considered in a manner similar to guideline-recommended non-invasive CRC screening options and can be completed during any healthcare visit. A positive Shield result raises concern for the presence of colorectal cancer or advanced adenoma and the patient should be referred for colonoscopy evaluation.About Guardant Health

Largest Published Study of Molecular Residual Disease (MRD) in Stage III Colon Cancer Shows Guardant Reveal Blood Test More Precisely Identifies Risk of Recurrence After Surgery to Support Timely Treatment DecisionsFebruary 2, 2026 8:05 AM
Business Wire

Data published in Journal of Clinical Oncology supports routine use of circulating tumor DNA (ctDNA) testing in management of stage III colon cancer patients



Guardant Health, Inc. (Nasdaq: GH), a leading precision oncology company and research collaborators at Mayo Clinic and the Alliance for Clinical Trials in Oncology today announced publication of the largest study to date evaluating circulating tumor DNA (ctDNA) for MRD detection in patients with resected stage III colon cancer after surgery and before adjuvant chemotherapy. Results of the study, published in the Journal of Clinical Oncology, show that detecting ctDNA with the Guardant Reveal® blood test better predicts recurrence and overall survival than standard staging.


Researchers found that about 20 percent of patients in the phase III trial, which was presented at the 2025 American Society for Clinical Oncology (ASCO) Annual Meeting, involving more than 2,000 patients still had detectable ctDNA in their blood after surgery. Guardant Reveal identified patients at a four-to-six-fold higher rate of disease recurrence or reduced survival. Even patients with smaller tumors or fewer affected lymph nodes found as part of traditional staging had an over 6-fold higher rate of events if ctDNA was detected. The findings support the integration of tissue-free ctDNA testing into routine postoperative management to better identify patients at high risk of recurrence who may benefit from intensified surveillance or alternative adjuvant strategies.


Measuring the amount of cancer DNA in the blood, a marker known as tumor fraction, further distinguished those at the highest risk of early recurrence and worse survival. This additional layer of information may help clinicians prioritize patients who need the most intensive surveillance or consideration of alternative therapies.


“The data suggest that not only the presence of ctDNA, but the amount of ctDNA, as identified by Guardant Reveal may help refine risk beyond standard TNM staging, and could be used to guide adjuvant treatment and surveillance decisions,” said Frank Sinicrope, MD, professor of oncology and medicine at Mayo Clinic and principal investigator for the study. “ctDNA testing after surgery improves the accuracy of estimating a patient’s risk of cancer recurrence, enabling more tailored recommendations for adjuvant chemotherapy and follow-up monitoring. It also identifies high risk patients who are likely to recur despite standard treatment, and who may benefit from alternative therapeutic approaches.”


“This large study adds to growing evidence that ctDNA testing with Guardant Reveal after surgery helps answer the question patients care about most: Am I really cancer-free?” said Dr. Craig Eagle, Guardant Health Chief Medical Officer. “Personalizing care after surgery is essential as clinicians and patients decide what comes next. Guardant Reveal fits easily into routine practice and provides timely, actionable insight—helping identify patients at high risk while sparing others unnecessary treatment and anxiety.”


Today’s announcement is the latest data reinforcing the clinical utility of Guardant Reveal in molecular residual disease and beyond. Guardant recently expanded Reveal to support late-stage therapy response monitoring, enabling ctDNA-based assessment of treatment effectiveness across solid tumors. This adds to evidence from early-stage breast cancer publications that Reveal’s tissue-free approach can identify patients at elevated risk of recurrence and support more personalized care.

GH, 10 day chart

New to the board. Evaluating whether to invest in Guardant Health or Exact Sciences.

After speaking with multiple gastroenterologists and family physicians, a clear consensus emerged: Cologuard Plus (Exact Sciences) is widely regarded as the more accurate test. In contrast, Shield (Guardant Health) is viewed as having a very limited clinical role—primarily for patients who refuse both colonoscopy and stool-based tests, a scenario described as rare in routine practice.

From an investment perspective, it's important to note that many providers consider Shield to fall below the standard of care due to its lower diagnostic accuracy. Several physicians mentioned the increased liability risk and emphasized that offering Shield requires significantly more documentation and patient counseling. Physicians must clearly outline its inferior performance compared to colonoscopy and stool-based testing, and thoroughly document that discussion to protect against potential malpractice exposure.

This added complexity—combined with Shield’s limited clinical niche—could pose serious barriers to widespread adoption, and is a critical factor for investors to weigh when considering the long-term viability of Guardant’s screening platform.

I am interested in your perspectives

GH, new 52 week high

GH 10Q due 4/30

GH buy the dip

GH that awful Cathie has been a recent buyer

I'm in, $33 ish I like the potential. Short wise only 6% of float and 6 million shares only 200 million so I don't think we'll see a squeeze like ASTS has been doing.

X. I just like to throw down a marker when I invest, I'm a long as in 80% of the time I hold shares for years and years many for decades.

The American biotechnology company Guardant Health, which produces liquid biopsy tests to detect cancer from mutations and other modifications in blood samples,[1] was co-founded by Helmy Eltoukhy and AmirAli Talasaz during 2012–2013.[2][3] According to John Dorfman of the Pittsburgh Tribune-Review, Talasaz and Eltoukhy discovered a technique which "involves detecting and monitoring tumor fragments circulating in the patient's bloodstream", as an alternative to traditional tissue biopsies.[4] The duo met at Stanford University in 2002 and worked together at Illumina, until Talasaz left in 2012.[5]

I would add GH with EXAS both would score on the final outcome. FDA is expected to decide whether to approve Shield later this year.

$GH Guardant Health Inc NASDAQ -Guardant Health to present real-world data supporting performance of Shield™ blood test for colorectal cancer screening at 2024 Digestive Disease Week
May 16 2024 - 8:05AM


Guardant Health, Inc. (Nasdaq: GH), a leading precision oncology company, today announced it will present data from two real-world studies at the 2024 Digestive Disease Week (DDW) meeting in Washington, DC, highlighting the value of the company’s Shield™ test in colorectal cancer (CRC) screening.

“One in three eligible American adults have not been screened for CRC, in part because the currently available methods are unpleasant or inconvenient,” said AmirAli Talasaz, co-CEO of Guardant Health. “The data we will share at DDW underscores the important role that our Shield blood test can have in both improving screening rates and in detecting more colorectal cancer at an early stage, when it is most treatable. We look forward to sharing this important data at DDW.”

GH—(-34%/AH)—reports_results_of “Shield” ctDNA—(liquid biopsy)—diagnostic_for colorectal cancer:

https://finance.yahoo.com/news/1-guardant-dna-blood-test-220041937.html

GH’s data aren’t bad, but they aren’t as good as those for EXAS’s Cologuard, which is based on a stool sample rather than a blood sample.

EXAS is +24%/AH, adding about $2B(!) to its market cap.

In #msg-168735158 (from May 2022), I said: Although GH says Shield is as good as EXAS’ Cologuard and MYNZ’s ColoAlert, I find it hard to believe that a blood test can be as sensitive for CRC (and precancerous lesions) as a stool-based test.I stand by that.

I'm still feeling very good about owning this stock. There is no way I'll sell this before the next five years.

I like the nice, gradual, consistent rise in the share price. I think there is no way to lose money here, and I think the gains will be very substantial over the next two to three years.

So am I. This is THE company I have chosen in which to put my investment dollars that I feel is both a high-growth situation and one in which I am certain not to lose money.

2-3 years I'm thinking this is @ 3-5X current share price
