Factor V Bethesda Units, Plasma
Use
This test is useful for detecting and quantifying the presence and titer of a specific factor inhibitor directed against coagulation factor V. Significant bleeding can result from the presence of a coagulation factor inhibitor, which could be life-threatening. It complicates the treatment process of a decreased factor level due to hemophilia or its acquired nature. The titer of the inhibitor may determine the mode of treatment. Bethesda units provide a standardization to give a uniform definition of an inhibitor.
