2种血细胞分析仪的实验室内比对结果分析

Analysis of in-laboratory comparative results between two kinds of hematology analyzer

目的分析XT-1800i与XS-1000i血细胞分析仪检测结果的一致性和可比性。方法按照美国临床实验室标准化委员会(NCCLS)的EP9-A2文件,以XT-1800i血细胞分析仪为比对仪器,与XS-1000i血细胞分析仪进行比对和结果分析。结果 XT-1800i与XS-1000i的白细胞(WBC)、红细胞(RBC)、血红蛋白(Hb)、红细胞比容(HCT)、平均红细胞体积(MCV)和血小板(PLT)的相关系数r≥0.975,医学决定水平处的系统误差均<1/2规定的允许总误差,中性粒细胞百分数(NEUT)、淋巴细胞百分数(LYMPH)、单核细胞百分数(MONO)、嗜酸性粒细胞百分数(EO)相关系数r≥0.975,但是嗜碱性粒细胞百分数(BASO)不具有相关性。结论 XT-1800i和XS-1000i血细胞分析仪WBC、RBC、Hb、HCT、MCV和PLT检测结果基本一致,可为临床提供准确一致的检验结果,但是对于白细胞分类结果,应重视其比对。

Objective Analysis of the consistency and comparability of test results of XT- 1800 i and XS- 1000 i hematology analyzer. Methods According to the U. S. Committee for Clinical Laboratory Standards（ NCCLS） of EP9- A2 document,we compared XT- 1800 i hematology analyzer with the XS- 1000 i hematology analyzer for comparison and analysis of results. Results The correlation coefficient of WBC,RBC,Hb,HCT,MCV and PLT were≥0. 975,the system error in medical decision level was less than 1 /2 of the allowable total error. The correlation coefficient of NEUT,LYMPH,MONO,EO were ≥ 0. 975,but BASO was not relevant. Conclusion WBC,RBC,Hb,HCT,MCV and PLT detection results of XT- 1800 i and XS-1000 i hematology analyzer are basically consistent,can provide clinically accurate and consistent test results,but for the classification of leukocytes,we shall increase attention to the comparability.
