Question

Quizplus · Accepted Answer

The prolonged APTT suggests a possible heparin contamination of the sample, leading to artificial prolongation of clotting times. The normal PT and TT support this interpretation as these are not affected by heparin contamination. DIC, Coumadin use, and liver disease would likely affect multiple coagulation assays, not just the APTT.
