Analysis of negative results of hepatitis B virus markers in healthy population in Hangzhou district / 国际检验医学杂志

ABSTRACT

Objective To analyse the distribution characteristics of negative pattern of hepatitis B virus Markers (HBV‐M ) in healthy population in Hangzhou district in 2014 ,and provide strategy for the prevention and control of HBV infection in HBV‐M negative population .Methods The HBV‐M (HBsAg ,HBsAb ,HBeAg ,HBeAb and HBcAb) in blood specimens of health examina‐tion population were tested by using ELISA .For 300 cases preserved HBV‐M negative specimens ,HBsAg and HBsAb were detec‐ted by using chemiluminescence immunoassay and HBV‐DNA was detected by using PROCLEIX ULTRIO? Assay .The viral load of HBV‐DNA reactive sample was quantitatively determined .Results Among 9 143 blood samples ,2 213 samples were HBV‐M negative ,and the negative rate was 24 .20% .The negative rate of male to female was 1∶1 .21 .Using chemiluminescence immunoas‐says and PROCLEIX ULTRIO? Assay simultaneously ,we found one case of low concentration of HBsAg(both HBsAb and HBV DNA nonreactive) ,four cases of low concentration of HBsAb(both HBsAg and HBV DNA nonreactive) ,two cases of HBV‐DNA reactive(HBV‐M negative) .One HBV‐DNA reactive sample could be quantified as 560 IU/mL .Conclusion In HBV‐M (ELISA) negative population of health examination of Hangzhou district ,a few subjects had low concentrations of HBsAg or HBsAb or HBV‐DNA .For HBV‐M negative population ,quantitative detection of HBV‐M and HBV‐DNA before HBV vaccination is recom‐mended to determine w hether they need HBV vaccine and the HBV vaccination plan .
