Reflotron-Hemoglobin干式血红蛋白检测系统的性能评价

摘要

Objective To evaluate Reflotron-Hemoglobin dry-chemistry system for the measurement of hemoglobin. Methods The within-run and between-run precisions, linearity, correlation and reference range of Reflotron-Hemoglobin dry-chemistry system was verified.Results The within-run precision was 2.54%-2.84%,and the between-run precision was 0.68%-3.38% for Reflotron-Hemoglobin dry-chemistry system,respectively.The linearity range was 52-191 g/L .The results of Reflotron-Hemoglobin dry-chemistry system were correlated well with those of Beckman-Coulter LH750 system,and the correlation equation wan Y=1.031 6X-2.796 9.The verification coincidence rate for reference range was 100%.Conclusions The within-run and between-run precisions of Reflotron-Hemoglobin dry-chemistry system for the determination of hemoglobin are good with accurate results for both normal and abnormal samples.The reference range can be used in this system.%目的：对Reflotron-Hemoglobin干式血红蛋白检测系统进行性能评价。方法对仪器的批内精密度、批间精密度、线性、相关性及参考范围进行验证。结果 Reflotron-Hemoglobin干式血红蛋白检测系统的批内精密度为2．54％～2．84％；批间精密度为0．68％～3．38％；线性范围为52～191 g/L；与 BECKMAN-COULTER LH750全自动血液分析仪的相关方程为 Y＝1．0316X-2．7969；参考区间验证符合率为100％。结论Reflotron-Hemoglobin 干式血红蛋白检测系统批内、批间精密度较好；在正常及病理范围内检测结果可靠；常用参考区间适用于本仪器。
