The Mindray BC-6800 automated hematology analyzer is an automated hematology analyzer and 5-part leukocyte differential counter for in vitro diagnostic use in clinical laboratories. It is necessary to undergo an evaluation before the instrument is used to test patient samples.
The performance was evaluated with regards to precision, linearity, carry-over, and method comparison. The flag performances were evaluated and compared with the Sysmex XE-2100 hematology analyzer and manual microscope in the hematology laboratory of a tertiary hospital in China.
There was minimal carryover (< 0.05%) and excellent linearity for white blood cells and platelet (PLT) counts (r > 0.999). The BC-6800 displayed very good correlation (r > 0.97) with the XE-2100 for blood cell count and cell differential parameters. In a comparison of 295 leukocyte differential count results analyzed in parallel with manual microscopy, the main flags (immature granulocytes, blasts, abnormal lymphocytes) showed approxi-mately the same sensitivity and specificity on both analyzers (sensitivity > 90%, specificity > 78%).
The BC-6800 showed excellent performance and supplied confidence in flag information for abnormal samples in the routine hematology laboratory.
迈瑞BC - 6800全自动血液分析仪是一款用于临床实验室体外诊断的全自动血液分析仪及五分类白细胞分析仪。在该仪器用于检测患者样本之前，有必要进行评估。
对该仪器的精密度、线性、携带污染和方法比对进行了评估。在中国一家三级医院的血液学实验室，对该仪器的报警性能进行了评估，并与Sysmex XE - 2100血液分析仪和手工显微镜进行了比较。
携带污染极小（<0.05%），白细胞和血小板计数的线性良好（r>0.999）。BC - 6800在血细胞计数和细胞分类参数方面与XE - 2100显示出非常好的相关性（r>0.97）。在与手工显微镜平行分析的295例白细胞分类计数结果比较中，主要报警项目（未成熟粒细胞、原始细胞、异常淋巴细胞）在两台分析仪上的敏感性和特异性大致相同（敏感性>90%，特异性>78%）。
BC - 6800表现出优异的性能，并为常规血液学实验室中异常样本的报警信息提供了可信度。
