摘要 目的 :对重组双抗原夹心法ELISA、全病毒间接法ELISA和免疫荧光分析法 3种SARS抗体诊断试剂盒进行临床应用效果评价 ,比较不同试剂的使用效果。方法 :使用 3种试剂检测了 2 5 7例临床确诊SARS患者的血清标本 2 79例和其他非SARS患者标本 2 4例、健康体检者血清标本 80份。结果 :临床确诊SARS患者发病 1~ 2 0d的病例中双抗原夹心法ELISA检出率最高 ,间接免疫荧光法与其接近 ,全病毒间接法ELISA检出率最低。在发病 2 0d后 ,三者检出率接近 (94 %左右 ) ,3种方法的符合率在 97%以上。在 10 4例非SARS病例中 ,双抗原夹心法ELISA和免疫荧光法均未见出阳性结果 ,全病毒间接法ELISA检出阳性结果 3例 ,假阳性率 2 .9%。结论 :检测SARS抗体双抗原夹心法ELISA试剂盒、免疫荧光试剂盒具有类似的灵敏度和特异性 ,其灵敏度和特异性高于全病毒间接法ELISA。
