• First FDA-approved, at-home screening test that uses RNA technology to detect biomarkers associated with colorectal cancer and advanced adenomas
• Designed to reduce common barriers to at-home screening with a cleaner, simplified collection experience that minimizes sample handling
• Meets screening guidelines from the American Cancer Society (ACS) and National Comprehensive Cancer Network (NCCN)

BURLINGTON, N.C. and ST. LOUIS, June 22, 2026 /PRNewswire/ -- Labcorp (NYSE: LH), a global leader of innovative and comprehensive laboratory services, today announced the nationwide availability of ColoSense®, the only RNA-based at-home test for colorectal cancer (CRC) screening approved by the U.S. Food and Drug Administration (FDA). Offered through a commercial collaboration with test developer Geneoscopy, ColoSense expands Labcorp's comprehensive portfolio of colorectal cancer screening solutions. The test is now covered for eligible Medicare and Medicare Advantage beneficiariesⁱ following the Centers for Medicare & Medicaid Services (CMS) update to the National Coverage Determination (NCD) in June, with additional commercial coverage also available.

Reducing Barriers to At-Home Screening
Colorectal cancer is highly preventable when detected early, yet approximately 4 in 10 eligible adults are not up to date with recommended screenings. While at-home tests offer convenience, the collection process can be a significant barrier to completion. According to Labcorp research, among users of at-home screening tests, 41% were uncomfortable preparing the sample, and 34% said the process felt messy. ColoSense is designed to reduce common barriers to at-home screening with a cleaner, simplified collection experience that minimizes sample handling.

"Labcorp is focused on improving colorectal cancer screening rates by offering at-home options consumers are more likely to complete," said Dr. Brian Caveney, chief medical and scientific officer at Labcorp. "With ColoSense now available nationwide, we're expanding access to an FDA-approved screening option that delivers advanced science and a more streamlined, easier-to-use collection experience."

Breakthrough Innovation Recognized by the FDA and Leading Cancer Authorities
ColoSense uses RNA-based technology to detect biomarkers associated with both colorectal cancer and advanced adenomas, precancerous changes that may be an early indication of disease. ColoSense received Breakthrough Device Designation from the FDA, which is reserved for medical devices that offer the potential for more effective diagnosis or treatment of life-threatening conditions. ColoSense aligns with stool-based RNA screening approaches recognized in the American Cancer Society (ACS) colorectal cancer screening guidelines and is included as a recommended screening option in the National Comprehensive Cancer Network (NCCN) guidelines.

"ColoSense reflects years of scientific innovation focused on improving how we screen for colorectal cancer at home," said Matt Sargent, chief commercial officer at Geneoscopy. "We're proud to partner with Labcorp to help bring this test into routine care nationwide and ensure more patients can benefit from earlier detection."

ColoSense is available through healthcare providers for adults aged 45 to 85 at average risk and is not for individuals with a history of colorectal cancer or certain high-risk conditions. ColoSense has demonstrated strong clinical performance, with 93% sensitivity for colorectal cancer in average-risk individuals, and achieved 100% sensitivityⁱⁱ for stage I colorectal cancer, detecting disease at its most treatable stage.

Once ordered, the collection kit is delivered directly to the consumer's home for collection and return, featuring a simplified design that eliminates the need to separate or mix the stool sample. Geneoscopy offers patient navigation support to help individuals understand their results and follow recommended next steps, including colonoscopy after a positive result. ColoSense is a screening test and does not replace diagnostic colonoscopy.

The introduction of ColoSense further expands Labcorp's portfolio of colorectal cancer screening options, providing patients and providers with greater choice and flexibility. To learn more, visit https://www.labcorp.com/treatment-areas/colorectal-cancer/crc-screening/colosense.
