Thrombin Mixing Study Test
This test
is used in the diagnosis of fibrinogen deficiency, both congenital
and acquired and to identify heparin contamination of samples.
Thrombin
time will be extended when functional fibrinogen levels are <100 mg/dL.
This can occur due to congenital conditions including afibrinogenemia (complete
lack of fibrinogen), hypofibrinogenemia, and in dysfibrinogenemia, a condition
characterized by the presence of dysfunctional fibrinogen. Acquired conditions
can lead to diminished fibrinogen levels and extended thrombin times include
liver disease, renal disease, disseminated intravascular coagulation (DIC),
amyloidosis, malignancy, and thrombolytic therapy. Thrombin inhibitors including
heparin, argatroban, and hirudin will cause an extended thrombin time.
A significant
deviation from the normal range may require further evaluation by your physician.
