SAINT PAUL, Minn., Sept. 29, 2026 /CourierPR/ -- Astrin Biosciences, a cancer intelligence company that uses deep proteomics and artificial intelligence to transform cancer detection and treatment, today announced that its Certitude™ breast cancer screening blood test is now available to eligible women across 48 states. This expansion, made possible through a new distribution partnership with OpenLoop Health, marks a significant step forward in providing women with a new tool for early breast cancer detection.
The Certitude™ test, a first-of-its-kind, non-imaging blood test, fills a longstanding void for women with dense breast tissue, a factor that both raises breast cancer risk and makes traditional imaging less effective at catching cancer early. Until now, many of these women have had limited additional options beyond supplemental imaging, which can be costly, time-consuming, and inconsistently accessible depending on where they live.
Certitude uses Astrin’s proprietary deep proteomic platform, analyzing thousands of proteins from a small blood sample to identify early molecular signals associated with breast cancer. A validation study of 1,242 women demonstrated that the test has a sensitivity of 92% and a specificity of 93%, with a negative predictive value greater than 99.9%.1 To check for eligibility and order the test, women can visit CertitudeTest.com.
The Certitude™ test is now available to women in 48 states, with New York and Hawaii having the option to check medical eligibility to see if Certitude is right for them and join a waitlist to be notified when the test becomes available in their state.
