We have encountered similar problems and have devised practices for minimizing them. The most important are the development of a close working relationship between interested clinicians and laboratory personnel and proper implementation of standardized heparin order sheets. After years of practice, our coagulation laboratory staff have become adept at calibrating the therapeutic aPTT range for new thromboplastin reagents. We have experienced several major shifts in aPTT therapeutic ranges over the years: Our lowest calibrated range was 46 to 70 seconds, and our highest was 75 to 105 seconds. The ...References1.
