title: Which coagulation factors interfere with the one-stage prothrombin time?
abstract: Coagulation factors that interfere with the one-stage prothrombin time (PT) were investigated. PT responded with identical activities (adequately) against coagulation factors VII or X, only half as expected against factor IX, less than expected and nonlinearly against factor II. In multiple coagulation factor deficiencies PT did not differ from factor VII, which was the most reduced coagulation factor in warfarin therapy or liver disease. PT may also be influenced by factor VII at high activities.
