Thrombin Clotting Time-Reference Range

Thrombin time (TT), also known as the thrombin clotting time (TCT), is a test used to evaluate the level and function of fibrinogen and to detect heparin contamination.

The normal ranges for thrombin clotting time are 12 to 14 seconds.

Prolonged thrombin clotting time may indicate:

  • Hypofibrinogenemia
  • Afibrinogenemia
  • Abnormal fibrinogen function (dysfibrinogenemia)
  • Disseminated intravascular coagulation (DIC)
  • Abnormal fibrinolysis impair fibrin formation
  • End stage liver disease
  • Malnutrition

It should be noticed that if thrombin clotting time is abnormal, additional tests such as fibrinogen activity assay, liver function tests and fibrinogen antigen assay are needed to diagnose diseases.
