【摘要】 目的 比较GICA与ELISA检测HBsAg的结果符合率，以了解GICA的特异性与敏感度。方法 用GICA和ELISA平行检测受检者血清标本HBsAg。结果 GICA和ELISA检测HBsAg的结果符合率为99.09%，GICA检测HBsAg存在漏检(即假阴性)。结论 GICA较ELISA敏感度低，用GICA检测HBsAg等项目存在一定程度的漏检率，GICA只能筛查HBsAg，检测HBsAg低含量的血清标本不宜使用；GICA快速诊断法可用于对献血员的现场筛查，血源应用ELISA初检或(和)复检，以保证血源安全。

    【Abstract】 Objective To compare the variation rate between GICA and ELISA for detecting serum HBsAg，thus to determine specificity and sensitivity of GICA.Methods Serum HBsAg in patients and volunteers was detected by GICA and the serum samples were also detected by ELISA as a control.Results The HBsAg accord rate between GICA and ELISA is 99.09% ......
