Part 1: Change from Baseline in Endogenous Thrombin Potential (ETP) (Thrombin Generation Assay [TGA] Parameter)
The TGA measures the thrombin generation that is indicative of an overall coagulating capacity. A calibrated automated thrombography is used to monitor the concentration of thrombin in clotting plasma with a fluorogenic substrate. The data derived from the thrombography can be used to determine the ETP (TGA parameter).
