This test may also be useful to determine Factor 10 Activity Deficiency in patients with Amyloidosis.
WebAnti-factor Xa activity test is used to monitor LMWH therapy because it behaves differently than UFH. Interestingly, while UFH is known to activate antithrombin’s effects against several of the activated intrinsic clotting factors, LMWH only inhibits factor X. LMWH is a shorter molecule and this simple difference is enough to make it so that ... WebJul 22, 2009 · The chromogenic assay of factor X is recommended for monitoring patients on warfarin when the INR cannot be accurately determined due to interference with the fibrin endpoint in the INR.

Webfactor X. Factor Xa then binds to factor Va to form prothrombinase, thereby increasing the rate of factor Xa–mediated conversion of pro-thrombin to thrombin 300 000-fold. The resultant burst of thrombin rapidly converts fibrinogen to fibrin, and fibrin monomers polymerize to form the fibrin mesh that is stabilized and cross-linked by factor ...
