Reptilase time

Reptilase Time

Reptilase time (pronunciation: rep-til-ase time) is a diagnostic test used in the field of Hematology to evaluate the blood coagulation process.

Etymology

The term "Reptilase" is derived from the enzyme Reptilase, which is obtained from the venom of the Bothrops atrox snake. The word "time" refers to the duration taken for the clotting process to occur when Reptilase is added to a blood sample.

Definition

Reptilase time is a measure of the time taken for a blood sample to clot after the addition of Reptilase. It is used to assess the function of Fibrinogen, a protein that plays a crucial role in blood clotting.

Clinical Significance

Reptilase time is often used in conjunction with other tests such as the Thrombin Time test to diagnose bleeding disorders. It is particularly useful in identifying abnormalities in the fibrinogen molecule or the presence of dysfibrinogenemia and Hypofibrinogenemia.

Procedure

The test is performed by adding Reptilase to a sample of the patient's blood and then measuring the time it takes for a clot to form. The normal range for Reptilase time is typically between 15 to 20 seconds.
