Three antigen-antibody systems are so far known to be related to viral hepatitis type B. Tests for evidencing HBsAg and antiHBs are easily performed and important for the diagnosis, prevention and study of hepatitis B. The tests for evidencing HBcAg and HBc are still the subject of study and research. The presence of HBsAg in a subject shows he is hosting hepatitis B virus. It may also be present without hepatopathy or it may be associated with acute or chronic hepatitis B. At the present time there is no feasible way of eliminating the chronic carrier condition. The problem represented by healthy carriers as infection risks is currently under study.
目前已知有三种抗原抗体系统与乙型病毒性肝炎相关。检测乙肝表面抗原（HBsAg）和乙肝表面抗体（抗HBs）的方法易于操作，对乙肝的诊断、预防和研究非常重要。检测乙肝核心抗原（HBcAg）和乙肝核心抗体（抗HBc）的方法仍在研究之中。一个人体内存在HBsAg表明其感染了乙肝病毒。它也可能在没有肝病的情况下出现，或者可能与急性或慢性乙型肝炎有关。目前尚无消除慢性携带者状态的可行方法。健康携带者作为感染源所带来的问题目前正在研究中。
