Abstract
INTRODUCTION: The Mindray BC-5000 automated hematology analyzer is a miniature, automated hematology analyzer, and 5-part leukocyte differential counter for in vitro diagnostic use in clinical laboratories. METHODS: Precision, linearity, carryover, and method comparison were carried out. The analyzer was evaluated and compared with the Sysmex XE-2100 hematology analyzer and manual microscopic in the hematology laboratory of a tertiary hospital in Chinese. RESULTS: There were minimal carryover (<0.25%), and excellent linearity for white blood cell, and platelet counts (r > 0.99). Within-run precision was good at all levels for the routine cell blood count parameters (CV < 3.5%). Between-run precision was acceptable at all levels for the analysis parameters (CV < 5%) except for eosinophil and basophil (CV% >10%). BC-5000 displayed very good correlation (r > 0.94) with the XE-2100 for cell blood count and cell differential parameters except for basophil (r = 0.72). The comparison of 258 leukocyte differential count results analyzed in parallel with manual microscopy, BC-5000 analyzer showed perfect specificity (93%) and negative predictive value (90%) on abnormal blood samples. CONCLUSION: It is concluded that the overall performance of the BC-5000 is acceptable. The miniature analyzer is suitable for use in small- to medium-size laboratories.
