Rapid tests (RTs) can be used as an alternative method for the conventional diagnosis of hepatitis B virus (HBV). This study aims to evaluate antibodies to HBsAg (anti-HBs) and antibodies to HBeAg (anti-HBe) RTs under different Brazilian settings. The following three groups were included: GI: viral hepatitis outpatient services; GII: low resource areas; and GIII: crack users and beauticians. Imuno-rápido anti-HBsAg™ and Imuno-rápido anti-HBeAg™ RTs were evaluated and showed specificities greater than 95% in all groups. The sensitivity values to anti-HBs were 50.38%, 51.05% and 46.73% and the sensitivity values to anti-HBe were 76.99%, 10.34% and 11.76% in the GI, GII and GIII groups, respectively. The assays had a low sensitivity and high specificity, which indicated their use for screening in regions endemic for HBV.
快速检测(RTs)可作为常规诊断乙型肝炎病毒(HBV)的替代方法。本研究旨在评估在巴西不同环境下针对乙型肝炎表面抗原(HBsAg)的抗体(抗-HBs)和针对乙型肝炎e抗原(HBeAg)的抗体(抗-HBe)快速检测。纳入了以下三组:第一组(GI):病毒性肝炎门诊服务;第二组(GII):资源匮乏地区;第三组(GIII):吸毒者和美容师。对Imuno-rápido anti-HBsAg™和Imuno-rápido anti-HBeAg™快速检测进行了评估,结果显示在所有组中特异性均大于95%。GI组、GII组和GIII组中抗-HBs的敏感性值分别为50.38%、51.05%和46.73%,抗-HBe的敏感性值分别为76.99%、10.34%和11.76%。这些检测方法敏感性低、特异性高,表明它们可用于HBV流行地区的筛查。
