INR blood test to measure blood clotting and natural ways to decrease or increase levels

INR define

Definition of INR

INR: International normalized ratio, is a standard for reporting the results of blood clotting tests. A person taking the anticoagulant warfarin might optimally maintain a prothrombin time (a “pro time” or PT) of 2 to 3 INR. No matter what laboratory checks the prothrombin time, the result should be the same even if different thromboplastins and instruments are used. This international standardization permits the patient on warfarin to travel and still obtain comparable test results.

INR level question
I am a 61 yr. old caucasian female. I had a heart attack on March 5th, 2006. I had angioplasty done on one artery in March 06. Since that time I have recuperated very well. When I left the hospital I was on 4 blood thinners, high blood pressure med, plavix and lipitor. By May/06 I weaned myself off of everything except warfarin and the blood pressure med. I coughed constantly until it was interfering with my sleep. I felt tired and lethargic all the time and was definately going backwards instead of improving. In the fall of 06 I weaned myself off of the blood pressure med and quit coughing. I felt better, more energy and life is worth living again. Three weeks ago I weaned myself off of warfarin. I began adding nattokinase to my daily regime along with Himalayan Goji Juice, Vitamin C, Calcium-Magnesium, & Omega 3. I am just starting to add garlic, vitamin E and Gingko. When I had my blood test my blood appeared to be quite thin and yet when they phoned me my INR they said I was only 1. They of, course upped my warfarin to 10 mg x 2 days, 6 mg x 2 days and 5 mg. the remainder. What I want to know is: Is there a difference between your thickness of the blood and the clotting time? I thought if your blood was thin the INR should be higher.
This is a good question. We are not sure if the INR covers all aspects of clotting, including platelets and other coagulation factors or whether certain actions of supplements thin the blood and reduce the chance of coagulation but do not necessarily raise the INR level.

How do Tribulus Terrestris and nattokinase, serrapeptase affect INR?
We need more studies to determine this effect.
