Abstract

In this study, the performance of a hematology analyzer, DxH 800 (Beckman Coulter, USA) was evaluated. The precision, carry-over, linearity, and comparison studies were performed according to the Clinical Laboratory Standards Institute guidelines. The test items were white blood cell, red blood cell, hemoglobin, red blood cell index, platelet, and reticulocyte counts. The 6C control and Retic-X cell control (Beckman Coulter) were used for precision evaluation. For the correlation study, the test results were compared with those obtained from the ADVIA 2120i (Siemens, USA) using 120 blood samples. The results of precision and carry-over evaluations were within acceptable range. The coefficient of determination (R 2) for linearity was good, being more than 0.99. The correlation coefficient (R) ranged from 0.945 to 0.996. DxH 800 was evaluated as an acceptable hematology analyzer for the automation of large volume of laboratory samples.
