The scenario '' Pt is on heparin therapy for DVT treatment. Last PTT 102 '' Question: Is this PTT a normal therapeutic range? The literature provides different answers. I am confused. Can you tell me what the range should be.According to my book aPTT = 20-39 Therapeutic range 1.5 - 2.5 normal.
Adenium 132 Posts Jun 11, 2011 Our hospital has a heparin protocol - docs can order a drip by protocol where we can adjust based on PTTs or order without protocol in which we give them the results and they order a new dosage. In any case the pt should have a baseline PTT for comparison. By our protocol we stop the drip for an hour for a PTT over 100, then restart at a specified lower dose and recheck PTT 6 hours later.

Some doctors wrote their own parameters. Every facility may be different, so check your facility for their protocol and P&P. 102 would definitely be high and we did also stop the infusion for one hour also. Good luck!Christy
