乙型肝炎病毒表面抗原定性检测阳性结果复检分析

目的　观察乙型肝炎病毒表面抗原 (HBsAg)检测结果的准确性 ,增强结果的可比性。 方法　对 30 6份HBsAg初检阳性结果进行复检。结果　 30 6份HBsAg初检阳性结果中 ,复检与初检一致者 2 82份 ,符合率为 92 16 % ;初检假阳性率为 7 84%。HBsAg结果复检符合率与初检OD值有关 ;HBsAg初检OD值越高 ,复检符合率亦越高。 结论　对HBsAg阳性结果进行复检 ,可以有效控制检测中影响结果的因素 ,对保证结果的准确性有重要意义。

Analysis of Repeated Determination Results for Positive HBsAg Patient using Qualitative Assay

Objective To observe the accuracy of hepatitis B surface antigen (HBsAg) determination results, to increase the comparability of HBsAg determination results. Methods To repeatedly determine 306 positive HBsAg cases. Results In 306 positive HBsAg cases, the positive repeated determination results were 282 cases, the coincidence rate was 92.16%. The false positive rate of primary determination results was 7.84%. The coincidence rate of HBsAg repeated determination results was related to the OD value of primary determination. The higher the OD value of HBsAg primary determination, the higher the coincidence rate of repeated determination results. Conclusion Repeated determining positive HBsAg cases can increase the accuracy of HBsAg determination results.
