| 摘 要： | 目的:建立一种基于光激化学发光分析（LiCA）技术定性检测血清CMV-IgM抗体的新方法。方法:利用CMV抗原包被的发光微球，生物素标记的鼠抗人IgM抗体以及链霉亲和素包被的感光微球共同构成完整的分析体系，优化反应缓冲液、抗原抗体工作浓度和待检血清稀释比例，并进行方法学评价和临床结果比对。结果:本方法的批内和批间变异系数为5.3%～6.1%和6.9%～9.8%，均小于10%；ROC曲线分析显示，曲线下面积为0.997，灵敏度为100%，特异度为98.9%；在100例血清样本的检测中，本方法与LIAISON检测结果符合率为95.0%。结论:成功建立了LiCA间接法反应模式定性检测CMV-IgM抗体的方法。该检测方法操作简单、快速、灵敏度高，有潜在的临床应用前景。

| Abstract: | Objective: To establish a light-initiated chemiluminescent assay (LiCA) for qualitative detection of CMV-IgM antibody in human serum. Methods: The assay was performed by incubating CMV antigen-coated chemibeads, biotinylated mouse anti-human IgM antibody and streptavidin-coated sensibeads. The assay buffer, working concentration of antigen and antibody and dilution ratio of serum were optimized. Furthermore, analytical performance was evaluated and the consistency of the results between LiCA and LIAISON was tested. Results: The intraassay and interassay coefficient of variation were both less than 10%, ranging from 5.3% to 6.1% and 6.9% to 9.8%. ROC curve analysis showed that the area under the curve, sensitivity and specificity were 0.997, 100%, and 98.9%, respectively. The accordance rate was 95.0% between LiCA and LIAISON in the measurement of CMV-IgM antibody in 100 serum samples. Conclusion: Indirect LiCA for qualitative detection of CMV-IgM antibody has been successfully established. The assay is simple, rapid, highly sensitive and has potential clinical prospects. |
