You say and I quote"When inr readings are low,Decrease Mg and when High increase. It seems to contradict what's said below and I quote " Taking a blood thinner will increase the INR number , but taking less blood thinner will take you back to your normal INR"
Kindly explain?

Cardio Files.Net states the following and I quote,"When INR readings are Low, Decrease Mg, and when High Increase" this appears to contradict what was stated below under 'Moderator" and I quote, 'Taking a blood thinner will increase the INR ie INCREASE the INR number, but taking less blood thinner will take you back to your normal INR. (The latter I believe is to a lower number)
Kindly explain what I had failed to consider?

CardioFiles.net did not state "When inr readings are low, ..." A guest poster did that. A guest poster who was clearly confused and needed to chat with his doctor

The time taken for blood to clot is called the "prothrombin time". Because of variability in prothrombin times with tests due to external factors, when a lab does a prothrombin test it actually tests a reference sample at the same time so, your test result is compared against the sample, The results are a simple ratio of your time divided by reference time. This is called the International Normalized Ratio.

So, if your blood takes the same time as the reference, the ratio is 1 INR, if it takes twice as long it's 2 INR, 3 times as long, 3 INR etc.

Since thinner blood takes LONGER to coagulate, then thinner blood means a higher INR number.

So, if you take more of a blood thinner, it will make your blood thinner and therefore will increase your INR number. If you take something that will make your blood thicker, it will lower your INR number.
