Tests for PROC and PROS added to the panel to supplement our thrombosis tests
As a supplement to our other thrombosis tests we now expand our analysis panel to include tests for Protein C (PROC) and Protein S (PROS). Together with our tests for the Factor V Leiden (FVL), Prothrombin 20210G>A and Methyl-Tetrahydrofolate Reductase 677C>T (MTHFR) genetic variants. PROC is a vitamin K-dependent plasma glycoprotein that is a key component of the anticoagulant system. Protein C is cleaved to its activated form, 'activated protein C' (APC) on endothelial cells by the thrombin-thrombomodulin complex. Protein S is a vitamin K-dependent plasma protein that inhibits blood clotting by serving as a nonenzymatic cofactor for activated protein C in the inactivation of procoagulant factors V (F5). and VIII (F8).
