30-36 seconds
On Heparin? 1.5-2.5x normal
High results mean the patient has a prolonged time forming a clot
PT
9-11 seconds
High results mean the patient has a prolonged time forming a clot
INR (normal, on warfarin)
<1.1
2-3 on warfarin
High results mean the patient has a prolonged time forming a clot
