A positive Hepatitis B Penta 25 is usually not serious. Hepatitis B Penta 25 positive, that is, surface and core antibodies are positive, which indicates that you have been infected with the hepatitis B virus, but due to your own high immunity, you have already cleared the virus, and the antibodies to hepatitis B will also appear. Hepatitis B P5 25 positive indicates the presence of hepatitis B surface antibody in the body, which is a protective antibody. As long as the concentration of hepatitis B surface antibody is tested regularly, if the concentration of antibody in the serum decreases or turns negative, then hepatitis B vaccination can be carried out to enhance one’s own immunity so as to resist the attack of the virus. If abnormal hepatitis B penta results are found, such as positive hepatitis B surface antigen, you need to consult a doctor in time and take treatment under the doctor’s guidance.
