APTT, PT, and INR

[bsugar888]

I know this may be a dumb question,but I know that

APTT 1.5 to 2.0

PT 1.5 to 2.5

INR 2.0 to 3

I want to know how do I get the theurp. levels for my patient

do I X by the patients base line...................I just dont understand can someone please walk me step by step....I'm very visual.

Thanks

The therapeutic levels are determined by the MD. For example coumadin dosing range can be different for different patients based on the MD and what he/she wants the INR to stay around. Their determination is based on the patient's dx. The patient's chart should have what levels the MD wishes to obtain.

When you say "I know that...".. what are these? Normal levels? Or targets? The anticoagulation targets depend on the patient conditions. I doubt APTT is 1.5-2.0, because normal is 25-40 secs. Do you mean they want APTT to be 1.5-2.0 times normal? This is often how the target is calculated. In that case, you would give heparin according to a nomogram to obtain APTT that is (1.5-2 x 25) = 37.5-50 to (1.5-2.0 x 40) = 60-80. This would be a very wide range and unusual.
