Make sure your Coumadin dosage and usage pattern is safe with regular visits to the Coumadin Clinic at Trinity Health System Twin City Medical Center. Our clinic makes it easy for you to get your international normalized ratio (INR) blood test results, with very little wait, and check your Coumadin dosage in a nearly pain-free way.

Coumadin is a life-saving drug that thins the blood for people that suffer from conditions like congestive heart failure, irregular heartbeat, and stroke, or for those that are at risk for blood clots.. However, Coumadin has been labeled as highly dangerous if people don’t take the correct dosage. Regular testing with real-time results allows medical professionals to adjust dosages
and minimize risk for patients.

This is the process you’ll follow when you arrive at your appointment at the Trinity Health System Twin City Medical Center Coumadin Clinic:

Quick Testing to Check Coumadin

  • Our clinic staff will use the fingerstick pinprick method, drawing one droplet of blood for the test.
  • Within a few minutes, we’ll have the results of your INR test.
  • The entire process, from start to finish, will last less than 30 minutes..

Low-Pain Testing Methodology

  • Instead of mining veins for a blood draw, which can often inflict a good deal of pain on the patient, the testing procedure inflicts minimal pain, and patients quickly become comfortable with the single finger prick used to get the droplet of blood.
