Hepatitis A weak positive includes hepatitis A antibody IgM weak positive and hepatitis A antibody IgG weak positive, both of them reflect different conditions, IgM weak positive usually need to be treated, and IgG weak positive usually suggests that the body is healthy at present. Hepatitis A antibody is the antibody produced after the body is infected with hepatitis A virus, which is divided into two kinds: IgM and IgG. IgM is produced after the body is infected with hepatitis A virus at the initial stage, and the weak positive hepatitis A IgM antibody suggests that the body may be in the stage of hepatitis A virus infection, so it can be intervened appropriately under the guidance of doctors and in combination with their own conditions, and because of the lack of specific drugs, it can be taken to improve immunity, liver protection, anti-virus and other programs. If hepatitis A virus IgG antibody is weakly positive, it suggests that the body has been infected with hepatitis A virus in the past, but now it has been cured and has protective antibody, only the titer of antibody is low, so it is still necessary to pay attention to avoid infection.
