Exact Sciences Corporation is a molecular diagnostics company focused on the early detection and prevention of colorectal cancer. The Company has developed a non‑invasive screening test called Cologuard for colorectal cancer. Its Cologuard test is a non‑invasive stool‑based deoxyribonucleic acid (DNA) (sDNA) screening test designed to detect DNA markers. In addition to DNA markers, its test includes a protein marker to detect blood in the stool, utilizing an antibody‑based fecal immunochemical test (FIT). The Company's Cologuard test is designed to detect pre‑cancerous lesions or polyps, and each of the four stages of colorectal cancer. By detecting pre‑cancers and cancers early with its test, affected patients can be referred to colonoscopy, during which the polyps or lesions can be removed. The company's test also detects blood in stool, utilizing an antibody based FIT test.
