Websamples identified — nearly five times higher than other causes, such as insufficient, incorrect, and clotted samples [10]. The American SocietyforClinicalPathology establisheda2%orlowerbenchmarkfor hemolysis rates among laboratory blood samples [9]. Hospital EDs have been identified as a major source of hemolyzed samples. Two Weband the time course of hemolytic reactions in media of different osmolalities is recorded. When erythrocytes lyse, the number of intact cells falls and consequently the turbidity of the medium diminishes. The recorded transmitance profile is a measure of the time course of hemolysis.
