乙肝表面抗原(HBsAg)阳性说明机体正感染HBV,可能是乙肝病人,亦可能为无症状携带者。无症状携带者患甲型肝炎时仍能检出HBsAg阳性,但所患并非乙型肝炎。乙肝表面抗体(抗-HBs)是保护性抗体,反映机体对HBV的抵抗力。乙肝核心抗原(HBcAg)存在于肝细胞核内,血液中不能检出。乙肝核心抗体(抗-HBc)在血中可检出,阳性说明机体正感染HBV,它是一个比HBsAg更敏感的感染指标。最近已能检测抗-HBcIgM,为乙型肝炎急性感染的标记。乙肝e抗原(HBeAg)存在于
Hepatitis B surface antigen (HBsAg) positive that the body is infected with HBV, may be hepatitis B patients, may also be asymptomatic carriers. Asymptomatic carriers still detect positive HBsAg when they develop hepatitis A, but not hepatitis B. Hepatitis B surface antibody (anti-HBs) is a protective antibody, reflecting the body’s resistance to HBV. Hepatitis B core antigen (HBcAg) exists in the nucleus of liver cells, blood can not be detected. Hepatitis B core antibody (anti-HBc) is detectable in the blood, and positive indicates that the body is infected with HBV, which is a more sensitive indicator of infection than HBsAg. Anti-HBcIgM has recently been detected as a marker of acute hepatitis B infection. Hepatitis B e antigen (HBeAg) exists in
