Description
Thrombin time measures clotting time of the last step in the coagulation
cascade, which is the conversion of fibrinogen into fibrin by thrombin.
Indications
The time necessary for fibrinogen to clot is affected by hypofibrinogenemia, dysfibrinogenemia and the presence of inhibitors of the fibrinogen-to-fibrin reaction (heparin, hirudin, fibrin degradation products and paraproteins). The test is used primarily to evaluate plasma specimens with prolonged activated partial thromboplastin time (APTT) values and, to a lesser extent, prolonged prothrombin time (PT). The test is also useful to detect quantitative and qualitative fibrinogen abnormalities.
