Just an INR. If they are breaking down the clotting mechanism to test then they would.

If I understand your question correctly, you want to know if you test for factor V before you start Coumadin. If that is correct, then the answer is yes. It is called an Activated Protein C (APC) resistance test. If you start Coumadin then you cannot do an APC resistance test. You will have to do a genetic test to determine if you have the factor V gene mutation. This test will determine if you have one or two copies of the gene mutation.

If you have issues maintaining a stable INR on Coumadin you should talk to your doctor about Xarelto, Arixtra, or Lovenox. The last two are injectables. I hope this answers your question.
