谢谢411老师这么及时的回复,纠正一下,不是HBEAG(-),而是HBSAG(-),而且是用雅培半定量法检查,多次检查均只有乙肝核心抗体阳性,其余均阴性,乙肝DNA小于检测值,是指小于1000. ...
Occult hepatitis B virus infection is defined as the presence of viral DNA in circulating blood without detectable HBV surface antigen (HBsAg). The frequency of this condition is directly dependent on the sensitivity of either or both assays. The prevalence will be maximum with an insensitive HBsAg assay and very sensitive genomic amplification method. At present, the third generation of tests led by the Abbott PRISM can detect HBsAg levels less or equal to 0.1 ng/ml and the most sensitive NAT by transcription mediated amplification or real time PCR (QPCR) can detect 10 IU/ml or approximately 50 copies of viral genome/ml. In the past few years, several excellent reviews have been published on the topic
