Lab Testing

A A A

The INR is a blood test that determines the dose of warfarin/coumadin you need.

We will do a finger stick to get the amount of blood needed for the test.

We can also draw blood for any other test ordered by your doctor. Please bring the order your doctor gives you to your clinic visit.

We will contact you with your lab results and any changes that need to be made in your warfarin/coumadin dosage.

If you do not hear from us the day you have your blood drawn, take your usual dose of warfarin/coumadin and we will call you the next day.

If you do not receive a call within 24 hours, please call us toll free (800) 667-1028.
