OverviewThe bleeding time test is used to evaluate how well a person's blood is clotting. The test evaluates how long it takes the vessels cut to constrict and how long it takes for platelets in the blood to seal off the hole. Blood vessel defects, platelet function defects, along with many other conditions can result in prolonged bleeding time.
