同一品牌不同类型血细胞分析仪的校准及比对分析

目的对该科室的迈瑞全自动血细胞分析仪进行校准及比对分析,确保实验结果的溯源性及一致性。方法使用具有溯源性的迈瑞公司配套校准品对该科室的迈瑞BC5800全自动血细胞分析仪进行校准,校准后进行校准验证,校准验证通过后对新鲜血标本进行定值,以定值新鲜血标本对迈瑞BC5300及BC5180全自动血细胞分析仪进行校准,然后进行校准验证。校准验证通过后,以BC5800为基准仪器,BC5300及BC5180为比对仪器进行新鲜血比对试验。结果迈瑞BC5800、BC5300、BC5180全自动血细胞分析仪校准后均通过校准验证,新鲜血比对试验中BC5800与BC5300,BC5800与BC5180的白细胞(WBC)、红细胞(RBC)、血红蛋白(HB)、平均红细胞体积(MCV)、血小板(PLT)、血细胞比容(HCT)、平均红细胞血红蛋白含量(MCH)、平均红细胞血红蛋白浓度(MCHC)相对偏差符合率均超过80%,比对试验通过。结论血细胞分析仪校准后必须进行校准验证和比对试验并通过比对,确保实验结果的溯源性和检验结果间具有可比性,以满足临床的需要。

Calibration and comparison analysis of same brand of different types of hematology analyzer

Objective To conduct the calibration and comparative analysis on the Mindray BC 5800 automated hematology analy-zer in our department for ensuring the traceability and consistency of experimental results .Methods The mating calibrator of the Mindray company was used to conduct the calibration in the Mindray BC5800 automated hematology analyzer ,after calibration ,the calibration verification was performed .After passing the calibration verification ,the fresh blood was conduct the fixed value ,then the Mindray BC5800 and BC5180 automated hematology analyzers were calibrated ,after calibration ,the calibration verification was conducted ,after passing the calibration verification ,with the BC5800 as the standard instrument and BC5180 as the comparison in-strument ,the comparison experiment of fresh blood was performed .Results The Mindray BC5800 ,BC5300 and BC5180 automated hematology analyzers were passed the calibration verification after calibration ,in the comparison experiment of fresh blood ,the rela-tive deviation coincidence rates of WBC ,RBC ,Hb ,MCV ,PLT ,HCT ,MCH and MCHC between BC5800 and BC5300 and between BC5800 and BC5180 all exceeded 80% ,the comparison tests were passed .Conclusion The hematology analyzer should be per-formed the calibration verification and comparison test after calibration ,and the comparison test must be passed for ensuring the traceability of results and comparability among the test results in order to meet clinical needs .
