摘要 目的保证全血细胞计数(complete blood count,CBC)检测结果的溯源性和准确性。方法参加卫生部临检中心建立的血细胞分析溯源体系,向卫生部临检中心参考实验室进行血细胞分析的溯源和比对。采用二级标准血液分析仪,用配套或卫生部临检中心参考实验室提供的定值新鲜血校准,并使用与参考实验室相同批号的全血质控物、定值乳胶微粒质控物(Cell- check-400)和氰化高铁血红蛋白标准液(HISTAN)作为比对物质进行质量控制,每月将全血质控物检测结果与参考实验室同期测定而提供的靶值进行比对,Cellcheck-400和HISTAN检测结果与其定值比对。结果全血质控物检测结果与靶值的相对偏差:WBC±4.5%内,RBC±5.5%内,HGB±2.5%内,HCT±4.0%内,PLT±6.8%内;Cellcheck-400和HISTAN检测结果与其定值相对偏差:RBC±3.5%内,MCV±4.3%内,HCT±4.0%内,HGB±1.8%内。结论二级标准血液分析仪检测结果的可比性良好,其溯源模式和质量控制方案保证了二级标准血液分析仪检测结果的溯源性和准确性。
