Certitude Breast blood test explained: a novel multi-analyte assay for early breast cancer detection

A new multi-analyte blood test (Certitude Breast) is being developed for early breast cancer detection, analyzing serum protein biomarkers and autoantibodies to distinguish malignant from benign disease. It is intended as a non-invasive adjunct to imaging, although published dia…

• Design: Early-stage development report and explanation of a novel liquid biopsy test; no diagnostic accuracy study results reported in the source.
• Technology: The test combines measurement of serum protein biomarkers with tumor-associated autoantibodies to create a multi-analyte signature.
• Limitation: No sensitivity, specificity, or AUC figures are provided; the test has not yet been validated in a prospective screening trial as reported here.
