I thought for this post a brief alert. I have suffered with blood clots in the past and it is for that reason I take Warfarin. It requires frequent blood tests, preferably monthly.
The blood test is called I.N.R, it tests for the clotting factor within the blood. Yesterday I had blood work done. The results were expected due to the fact I have been on some new prescriptions. It was a very high number, normal rate they like to see is around 2.5. Mine was 4+, so adjustments had to be made to my daily regiment of Warfarin.
I am writing this post to bring attention to those who take prescriptions, who need blood tests. If your blood work is coming back with strange results maybe you should speak with your physician so that he can adjust your regiment of medications.
When I was first put on Warfarin over ten years ago I did not understand the correlation between Warfarin and the I.N.R. For more information about I.N.R you can find it here: Health Direct
A short description is this: An INR test measures the time for your blood to clot. It is also known as prothrombin time, or PT. It is used to monitor blood-thinning medicines, which are also known as anticoagulants. The INR, or international normalised ratio, can also be used to check if you have a blood clotting problem.
So dear reader from my experience prescription medicines can affect blood tests. Do not be alarmed, speak to your physician and your pharmacist!
