Overview of Blood Clotting Disorders
Tests of Blood Clotting
One commonly tested measure that affects the body's ability to stop bleeding is the count of the number of Platelets . Less often, doctors test how well the platelets function. Other tests can measure the overall, coordinated function of the many proteins needed for normal blood clotting (clotting factors). The most common of these tests are the prothrombin time (PT) and the partial thromboplastin time (PTT). The levels of individual clotting factors can also be determined.
