目的分析国产试剂与进口试剂检测乙型肝炎病毒表面抗体(抗-HBs)结果差异。方法选取新乡市中心医院住院和门诊病人血清标本44份,分别用罗氏全自动化学发光试剂和郑州安图生物化学发光试剂测定抗-HBs浓度,挑选阴阳性结果有差异的样本,再用国内主流试剂进行复测。结果郑州安图生物和罗氏试剂检测结果一致的百分比为95.5%,其中2份样本罗氏阴阳性结果与国内试剂存在反差。结论国产试剂与进口试剂检测抗-HBs结果存在一定的偏差,在一定程度上与包被和标记用HBsAg有关。
Objective To analyze the differences of the results of detection of hepatitis B virus surface antibody (anti-HBs) between domestic reagents and imported reagents. Methods Forty-four serum samples from inpatients and outpatients in Xinxiang Central Hospital were collected. The concentrations of anti-HBs were determined with Roche Automated Chemiluminescence Reagent and Zhengzhou Antu Biochemiluminescence Reagent, respectively. The samples with different positive and negative results were selected, Retest reagent. Results The percentage of test results of Zhengzhou Antu Biological and Roche Reagents was 95.5%, of which two samples were positive and negative with domestic reagents. Conclusion There is a certain deviation between the results of domestic and imported reagents in detecting anti-HBs, which is partly related to the coating and labeling of HBsAg.
