ThrombinzeitTest
The thrombin time test (TT), sometimes referred to by its direct translation ThrombinzeitTest, is a coagulation assay that measures the conversion of fibrinogen to fibrin after the addition of thrombin to citrated plasma. The result depends on fibrinogen level and function and is highly sensitive to substances that affect thrombin activity, such as inhibitors or contaminants.
Procedure: A standardized amount of thrombin is added to plasma, and the time to clot formation is
Clinical uses and interpretation: TT is used to detect abnormalities in fibrinogen, including low fibrinogen levels
Limitations and considerations: TT is highly sensitive to heparin contamination in the specimen and to assay
