Key facts

Thrombin peak [Molar amount] in Platelet poor plasma by Chromogenic method

Thrombin peak

The peak thrombin is the maximum thrombin measurement during a thrombin generation test. Decreased peak thrombin is associated with bleeding tendencies, while increased peak thrombin is associated with thrombosis. [PMID21262433]
