全自动血型分析仪与微板法在ABO血型筛查中的比较分析

目的探讨Beckman Coulter PK7300全自动血型分析仪与微板法在ABO血型筛查中的应用效果。方法选取2016年1-5月无偿献血者EDTA抗凝全血标本12 000例,采用Beckman Coulter Pk7300全自动血型分析仪和STAR加样微板手工比色法分别进行检测分析。结果两种方法检测ABO血型的准确率差异无统计学意义(P0.05)。在ABO血型筛查中,Beckman Coulter Pk7300全自动血型分析仪ABO亚型和抗体减弱的检出率均高于微板法。3例ABO血型正反定型在Beckman Coulter Pk7300全自动血型分析仪检测中一致而在微板法中不一致,4例ABO血型正反定型在Beckman Coulter Pk7300全自动血型分析仪检测中不一致而在微板法中一致。结论 Beckman Coulter Pk7300全自动血型分析仪能够安全有效对献血者进行ABO血型筛查,检测结果可疑的标本仍需结合试管法进行人工判读。

Comparative analysis of automatic blood group analyzer and microplate method in ABO blood group screening

Objective To investigate the application effect of the Beckman Coulter PK 7300 automatic blood group analyzer and the microplate method in ABO blood group screening .Methods A total of 12000 EDTA anticoagulation whole blood samples from January to May 2015 were collected from voluntary blood donors .The Beckman Coulter Pk7300 automatic blood group analyzer and STAR sampling microplate manual colorimetric method were to conduct the detection analysis .Results The accuracy for detecting ABO blood group had no statistically significant difference between the two methods (P>0 .05) .In the ABO blood group screening , the detection rates of ABO subtype and antibody weakening in the Beckman Coulter Pk 7300 automatic blood group analyzer were higher than those in the micro plate method .3 cases of ABO blood group typing and reverse typing were consistent in the detection by the Beckman Coulter Pk7300 automatic blood group analyzer ,but was inconsistent in the detection by the microplate method .4 cases of ABO blood group typing and reverse typing were inconsistent in the the detection by the Beckman Coulter Pk 7300 automat-ic blood group analyzer ,but was consistent in the detection by the microplate method .Conclusion The Beckman Coulter Pk7300 automatic blood group analyzer can safely and effectively conduct the ABO blood group screening in blood donors .The samples of suspicious detection results still need to conduct the manual interpretation by combining with the test tube method .
