How the INR Test Is Done :
When your doctor recommends a INR test, you'll likely undergo a simple blood draw specifically to measure INR levels. A pathologist, a specialist in disease study, will collect a small blood sample from your veins using a needle. Your INR test results are typically available within a few hours after the procedure.
