Does INR have a unit of measure ?? I know Pt and PTT are measured in seconds, but don't know about INR.

Thanks !!

Thanks! The answer to my question is: there is no unit of measure for INR.

Also... just realized I made a mistake by typing PTT instead of PT.

Thanks again Esme12 !!!

My instructor taught us a really neat trick- When you write ptt the two t's close together look like an H. The H stands for heparin. That's how you remember that PTT is associated with heparin and PT with warfarin.

I used to teach that TT-looks-like-H thing too. The other one is there's an O in COumadin (warfarin), which can remind you of prO time (the test they use to manage warfarin).
