摘要 目的研究分析HCV-cAg(丙型肝炎病毒核心抗原)ELISA检测方法在诊断丙型肝炎病毒上的临床应用价值。方法以我院2011年4月至12月住院及门诊患者的70例HCV-Ab阳性标本、240例HCV-Ab阴性样本为研究对象,通过HCV-cAg检测法和HCV-RNA PCR定量分析法同时对HCV-Ab(-)、(+)标本进行检测,以HCV-RNA检测值为对照值,比较分析HCV-cAg检测法在临床上诊断丙型肝炎病毒的意义。结果本文240例HCV-Ab阴性标本,经HCV-cAg检测阳性标本4例,阳性率检出率为1.7%;70例HCV-Ab阳性样本中HCV-cAg阳性37例,检出率为52.9%,HCV-RNA检出的阳性标本为43例,阳性率为61.4%,HCV-cAg与HCV-RNA的符合率为87%;同时以HCV-RNA检测值为对照,可知HCV-cAg检测法的特异性与HCV-Ab(89.5%)比较高达97.4%,敏感性高达85.4%。结论 HCV-cAg ELISA检测法与HCV-Ab比较具较高的特异性和敏感性,并可有效缩短HCV临床诊断的窗口期;HCV-cAg可联合HCV-Ab检测方法对HCV的早期诊断出更加准确的判断。
