RE: [SPAM] PT - INR safe values for Tx

I have always understood the INR to be the normalized version of PT results.

Different labs use different reagents to perform the PT test and therefore

different results could occur among labs. The INR equation is the attempt

to normalize this data so comparisons can be made across all labs. A normal

INR for someone on anticoagulation meds is 2 - 3. Therefore, I see the PT

as " raw " data and the INR as the " useful " clinical data.

Subject: [sPAM] PT - INR safe values for Tx

Can somebody please tell me the safe values/range for PT -INR in Acute

Care Setting? Some MDs say that as long as the INR is within 2.0 and

3.0 it doesn't matter how high is the PT. Also, got many different

info. fro colleagues. Any Evidence Based Practice or data about it?

Thanks in advance!
