The nurse from my rheumatologist's office called back and said they are sending me a prescription for an INR test and a PT(Prothrombin Time) . She said she doesn't do the homocystein levels or the fibrinogen test. I already had my cholesterol checked and everything was good. These are all tests that I heard can predict your blood's clotting possibility when you have antiphospholipid antibodies. I will probably go for the tests in a few days.
