Preop Clinic

A PT/PTT/INR test measures the clotting time and ratios of the blood. If the time is high, surgery maybe postponed, to prevent massive blood losses. The physician may have a few days go by and test you again. Surgery maybe rescheduled or cancelled. If you take Aspirin, Ibuprofen, or Coumadin, talk with your surgeon about these medications and your clotting tests.
