BECKM AN PK7300全自动血型检测系统可疑结果的原因分析

目的：探讨BECKMAN PK7300全自动血型检测系统在血站实验室用于血型筛查时出现结果可疑的原因以及应用中的注意事项。方法选取天津市血液中心2015年5月至2015年8月ABO及Rh血型经微板法鉴定后的无偿献血者的标本14417例，再由PK7300进行检测，统计分析ABO及Rh血型结果判读的正确率、错误率以及对可疑结果的原因进行分析。结果ABO血型结果一次性判读正确率为99．01％，失败率0．99％（其中正反定型不符0．48％），无错误判读；Rh（D）血型正确判读率100％。结论 BECKMAN PK7300全自动血型检测系统结果准确可靠，实现了血型检测的自动化、标准化，减少人为因素对实验的影响，反应图像可长期保存，保证结果的可溯性，节约成本，适用于血站实验室血型批量化检测需要。

Analysis the causes of suspicious results for BECKMAN PK 7300 automatic blood inspection device

Objective To investigate the causes of suspicious results for BECKMAN PK 7300 automatic blood inspection device on blood typing in blood station and the application notes .Methods A total of 11417 samples from unpaid blood donors were re‐cruited from Tianjin Blood Center between May 2015 and August 2015 .Microplate assay was applied in ABO and Rh(D)blood typ‐ing .All the samples were tested by BECKMAN PK7300 automatic blood inspection device .The accuracy and error rates were calcu‐lated for ABO and Rh(D)blood group and causes of suspicious results were analyzed .Results The accuracy and failure rate of ABO blood group were 99 .01% and 0 .99% (of which the inconsistent rate of positive and reverse ABO blood typing was 0 .48% )and there was no false reading .Its accuracy was 100% in Rh(D)blood grouping .Conclusion The results of BECKMAN PK7300 auto‐matic blood inspection device were accurate and reliable .The whole system achieved automation and standardization and reduced the artificial factors for experiments ,which images could be saved for a long period of time ,saving the cost .The analyzer was suitable for blood type batch testing in the laboratory of blood station .
