查询词典 markers

Sometimes, they showed seronegative for all HBV markers. The definition of occult HBV is based on the existence of HBV DNA in the serum, lymphatic cells and/or liver tissue in the absence of serum HBsAg.

隐匿性HBV感染的定义为在血清学检测HBsAg阴性的情况下，在感染者的血清、淋巴细胞和/或肝组织标本中检测到HBV DNA的存在。

The frequency of CMV seronegativity showed a stepwise decrease with the increase of donor age. In addition, the prevalence of HBsAg, antibodies to hepatitis C virus, antibodies to human immunodeficiency viruses type 1 and 2 (anti-HIV 1+2) and antibodies to human T-cell lymphotropic viruses type I and II (anti-HTLV 1/11) were compared between CMV seropositive and seronegative groups. Our results showed that there was no significant difference in seroprevalence of these markers between CMV seropositive and seronegative groups.
