Quizplus · Accepted Answer

The prothrombin time is a test that measures coagulation by assessing fibrinogen and clotting factors V, VII, and X. This type of test may be performed in at-risk patients to determine clotting abilities, outcomes of certain types of medication, and risk factors for surgery. The patient with decreased coagulation may need to have surgery postponed, depending on the procedure.
