The BT CT test, which is short for Bleeding Time and Clotting Time test, is used to check the amount of time taken by your blood to clot in order to stop bleeding. Most people never get this test done, but it is beneficial for those who are battling a case where bleeding, even from a small cut, does not stop. The test involves making small, shallow cuts on your skin to assess how well do your platelets work to clot blood in case of bleeding. Platelets are cell fragments in the blood that are the first to react in case of an injury to the blood vessel by sealing the wound; this helps prevent excess blood loss. Coagulation Disorder, Epistaxis and Platelet Disorder are checked in the test.
