Evaluation of sysmex automated hematological analyzer (KX-21N)‎ for the measurement of blood hemoglobin level

Abstract EN

This study was carried out on twenty normal subjects (women) in order to evaluate (Sysmex Automated Hematological Analyzer KX-21N) for the estimation of blood hemoglobin level. Two processes where used for evaluation, the first is the systematic error to determine the accuracy of the device by comparison with the standard device (the Sahli's) and the second process is to test the random error or reproducibility of Sysmex. The result of this study indicate that values of Hb measured by Sysmex KX-21N were slightly higher than that measured by Sahli's method (P < 0.005) And the result of random error test indicates that the Sysmex KX-21N is reproducible device which is improved by using the statically equation : (2 SD / mean x 100 %) to determine 95 % tolerance limit of the device which indicate that the device is greatly reproducible.
