Still wish there weren't so many abbreviations! Except CCSVI is ok since it takes forever to even say.

INR has to do with blood clotting time, and is measured when on coumadin. It stands for /international Normalized Ratio.

Just to toss my .02 in, INR won't vary between labs, hence the "International Normalized" part. PT and PTT can vary quite a bit depending on what lab and where, the INR won't. (or shouldn't). That's why they use it, but still we get the PT tossed in there for posterity. Both will go up and down in unison. INR readings of 1 are average joe/jane, 2 would be blood that is twice as thin, 3 is 3 times, so on so forth.
