WebOct 1, 2024 · Chromogenic factor X is a laboratory test that measures the percentage of factor X activity. Because testing is not dependent on thromboplastin or fibrinogen, CFX testing bypasses in vitro interactions that could lead to a falsely elevated INR. Warfarin inhibits hepatic synthesis of factor X. WebChromogenic factor VIII activity is used for diagnosis of mild hemophilia A (in conjunction with one-stage clot-based factor VIII activity) and measurement of factor VIII activity in the presence of interfering drugs or lupus anticoagulants that result in underestimation by clot-based methods.
