Hepatitis B surface antigen antibody is positive

Hepatitis B surface antigen antibody refers to hepatitis B virus surface antigen and hepatitis B virus surface antibody. Both positive may be related to reagent test error, acute hepatitis B infection stage, simultaneous infection with two subtypes of hepatitis B virus and other reasons. 1. The reagent test is incorrect. Generally, the surface antibody is positive, and other indicators are negative. There is a possibility that the reagent has problems, and false positives are prone to occur. In this case, it is recommended to go to the hospital for further quantitative detection of hepatitis B. 2. In the acute phase of acute hepatitis B infection, the virus replicates rapidly, and the elevation of transaminase leads to the destruction of liver cells, so that antigens appear on the surface. At the same time, the body produces immunity, antibodies appear on the surface, and the antigens and antibodies are positive when detected. 3. Simultaneous infection of two subtypes of hepatitis B virus When infected by two viruses at the same time, the body produces antibodies to one of the virus strains, but has no ability to resist the other strain, resulting in antigen on the surface of hepatitis B after infection. At this time, the antigen antibodies on the surface are positive. In addition to the above reasons may also be hepatitis B antiviral treatment process, the surface antigen value decreased, resulting in antibody positive. Discomfort symptoms in time to the hospital for standardized treatment, usually appropriate exercise, do not drink, protect liver function.
