Prothrombin time (PT) and activated partial thromboplastin time (APTT) are tests that evaluate the release of specific clotting factors by measuring the time it takes for a clot to form after certain reagents are added to a blood sample.
Bleeding time test. This test measures the time taken for blood vessel constriction and platelet plug formation to occur. No clot is allowed to form, so that the arrest of bleeding depends exclusively on blood vessel constriction and platelet action. Observe and listen to the procedure for determining bleeding time.
