Factor II (Prothrombin) Activity

Factor II (Prothrombin) Activity

Factor II, also known as prothrombin, is an essential protein in the blood that plays a critical role in the clotting process. It is a precursor to thrombin, which is a key enzyme that converts fibrinogen to fibrin – the primary component of blood clots. The Factor II Activity test measures the level and functionality of prothrombin in the blood, and it is a crucial test for evaluating the blood's ability to clot properly.

Factor II activity can be affected by various factors, including genetic mutations, liver disease, vitamin K deficiency, and the use of certain medications such as anticoagulants. Abnormal levels of Factor II can result in excessive bleeding or clotting disorders. The test is essential in diagnosing and managing conditions such as deep vein thrombosis, pulmonary embolism, and Factor II deficiency, which is a rare bleeding disorder.
