Hendrik Orman asks, “We are seeing more low aPPT results (less then 20) from ER, same with the redraw. Today, we gad 18.9 with repeat 15.3. Is there anything like medication etc. that might cause this?”
Hello, Hendrik, and thank you for your question. I’ll refer you to a recent series of posts and references from Drs. Favaloro and Koustosov on this subject. I hope their information answers your question.
