Thrombin Clotting Time with Reflex to Mixing Study
Use
This test measures the time it takes for plasma to form a clot after the addition of thrombin. If the Thrombin Clotting Time exceeds 23 seconds, a reflex mixing study is performed to help evaluate causes of prolonged clotting, such as the presence of inhibitors or dysfibrinogenemia.
