Activated Protein C Resistance

Activated Protein C Resistance


The Activated Protein C Resistance (APCR) test measures how your blood responds to activated protein C, a natural anticoagulant that helps prevent excessive clotting. Reduced sensitivity to activated protein C may increase the risk of developing blood clots in veins or arteries. This test is often recommended for individuals with a personal or family history of clotting disorders or unexplained thrombosis.
