Protein C Activity Test with Reflex to Protein C Antigen

The Protein C Activity Test with Reflex to Protein C Antigen measures the functional activity of Protein C, a vitamin K–dependent anticoagulant that regulates clot formation. Low Protein C activity can increase the risk of abnormal blood clots and may result from congenital deficiency, liver disease, or vitamin K deficiency. Reflex testing to Protein C antigen helps distinguish between quantitative and functional deficiencies.
