rockrock reacted to nziegler in mixing study criteriaWhat do you use as a cut-off point for an aPTT to reflex to a mixing study? Our current policy is to perform a mixing study on every pre-surgical patient with an "elevated" PTT. Elevated = anything above the normal cutoff. So with 36 seconds being our high end of normal, a 36.1 is reflexing a mixing study.
I haven't had much luck finding what other's are doing.....
