Factor X11 (Hageman) Activity, Plasma

Description

The Factor XII (Hageman) Activity test measures the level and function of Factor XII in plasma. Factor XII is part of the intrinsic coagulation pathway and contact activation system. While deficiency rarely causes bleeding problems, it can affect certain coagulation tests. This test is useful in evaluating abnormal coagulation test results, assessing risk for thrombosis in some conditions, and investigating certain autoimmune disorders. The results help in understanding the overall function of the coagulation system.
