Hepatitis B Penta 2 and 5 positivity means that the hepatitis B infection has returned to normal, and there are rare cases where the hepatitis B virus has mutated and you are still a hepatitis B patient. Hepatitis B 5 2 and 5 positive refers to hepatitis B surface antibody, hepatitis B core antibody positive, for the vast majority of people, this situation is normal. It means that the body has produced antibodies to clear the virus after infection with hepatitis B, and has returned to normal and now has protective antibodies. Hepatitis B virus is a DNA virus and is prone to mutation during replication. If the hepatitis B virus undergoes S antigen mutation, although infected with hepatitis B, it can be manifested as hepatitis B surface antigen negative, at this time, there is still hepatitis B virus in the organism, which is hepatitis B infected. In this case, it is necessary to complete the examination of hepatitis B viral load. If the hepatitis B viral load is positive, it means that the hepatitis B penta 2 and 5 positivity is caused by the mutation of the hepatitis B virus, and the person to be tested is still a hepatitis B patient. If the Hepatitis B viral load is negative, it means that the patient is not infected with Hepatitis B. When a positive Hepatitis B Penta 2 and 5 is detected, a visit to the Hepatology Clinic should be made.
