Factor X Assay, Plasma

Factor X, a glycoprotein of the intrinsic and extrinsic pathways of blood coagulation, is a serine protease composed of a light and a heavy chain. The factor X zymogen is activated by factor IXa or factor VIIa and converts prothrombin to thrombin. For the gene and protein levels, factor X is similar to other vitamin K-dependent proteases, particularly to factor IX and protein C. See Also Factor VIII:C Assay, Plasma and Factor IX Assay, Plasma

Factor X deficiency is a coagulation disorder with a variable bleeding pattern and is inherited as an autosomal recessive trait. Acquired factor X deficiency can occur secondary to amyloidosis.
