Thrombomodulin-modified Thrombin Generation Assay (TGA-TM) in Patients With Critical Infections

"TGA via a fluorimetric module. Coagulation cascade is activated upon addition of different concentrations of tissue factor and phospholipids. The fluorogenic substrate Z-Gly-Gly-Arg-AMC (ZGGR-AMC) is cleaved by formed thrombin over time. By plotting the changes in fluorescence as a function of time (cnt/min), it depicts the Thrombin Generation Curve (thrombin generated - plotted against time). The area under the thrombin curve is defined as the endogenous thrombin potential (ETP)."

Recombinant Human Thrombomodulin (TM) is added to the conventional TGA. When recombinant TM is added, the protein C system is fully activated and therefore the ETP obtained reflects both the anti- and procoagulant factors.
