Hepatitis B minor tri-positive is an old name that is no longer used. Hepatitis B minor tri-positive actually means that the five tests for hepatitis B show three positives for hepatitis B surface antigen (HBsAg), hepatitis B e antibody (anti-HBe) and hepatitis B core antibody (anti-HBc). Positive hepatitis B surface antigen: Hepatitis B surface antigen can be positive after 2 weeks of hepatitis B virus (HBV) infection, reflecting current hepatitis B virus infection, but negative cannot exclude hepatitis B virus infection. Hepatitis B surface antigen can persist for years, even for life, in asymptomatic carriers and chronic patients. Hepatitis B surface antigen itself is only antigenic and not infectious. Hepatitis B e antibody positive: indicates that the virus replication is mostly in a quiescent state and the infectiousness is reduced, but some patients have virus replication and hepatitis activity. However, long-term positive hepatitis B e antibody does not mean that virus replication has stopped or is not infectious. The hepatitis B core antibody is positive: almost all people infected with the hepatitis B virus can detect hepatitis B core antibody, hepatitis B core antibody IgM is an antibody that appears earlier after HBV infection, positive suggests the acute phase or an acute attack of chronic hepatitis. Therefore, hepatitis B minor triple yang means that the hepatitis B surface antigen, hepatitis B e antibody and hepatitis B core antibody are all positive, suggesting that the patient is infected with hepatitis B virus, but the virus replication is in a quiescent state and the infectivity is low.
