In order to study the relation of HBcAg in serum with five HBV serologic markers (HBsAg,Anti-HBs,HBeAg,Anti-HBe and Anti-HBc),Anti-HBcIgM and various types of hepatitis B,We tested 676 sera for HBcAg with RIA.

• 用 RIA 法检测了676份血清的 HBcAg,探讨了 HBcAg 与 HBV 五项血清学标志(HBsAg、抗-HBs、HBeAg、抗-HBe 和抗-HBc),抗-HBcIgM及各型乙型肝炎的关系。
