Abstract

Serology improves influenza diagnosis by capturing cases missed by reverse transcriptase PCR (RT-PCR). We prospectively evaluated microneutralization and hemagglutination inhibition assays for 2009 influenza A (H1N1) virus diagnosis among 24 RT-PCR-confirmed cases and 98 household contacts. Compared to hemagglutination inhibition, microneutralization demonstrated a higher level of concordance with RT-PCR (kappa = 0.69 versus kappa = 0.60) and greater sensitivity (83% versus 71%; P = 0.016).

摘要

血清学通过捕捉逆转录酶聚合酶链反应(RT-PCR)漏诊的病例来改善流感诊断。我们前瞻性地评估了2009年甲型H1N1流感病毒诊断的微量中和试验和血凝抑制试验,研究对象为24例经RT-PCR确诊的病例和98名家庭接触者。与血凝抑制试验相比,微量中和试验与RT-PCR的一致性更高(kappa值分别为0.69和0.60),敏感性也更高(分别为83%和71%;P = 0.016)。
