Warfarin (Coumadin®) is a "blood-thinner" (anticoagulant), a drug that is commonly prescribed to help prevent inappropriate blood clotting (thrombosis and thromboembolism) in individuals who are at risk or to help keep an existing blood clotting condition from getting worse. Warfarin sensitivity testing helps determine if a person may be more sensitive (i.e., require lower doses) or, less commonly, resistant (i.e., require higher doses) to treatment with warfarin because of his or her genetic makeup.
