Hepatitis B antibodies are checked by drawing blood to check the indicators of the Hepatitis B Pentathlon. Hepatitis B Penta includes Hepatitis B Surface Antibody, Hepatitis B Surface Antigen, Hepatitis B Core Antibody, Hepatitis B e Antibody and Hepatitis B e Antigen. Hepatitis B antibodies include Hepatitis B surface antibody, Hepatitis B core antibody and Hepatitis B e antibody. If the blood test shows that Hepatitis B surface antibody is positive, it suggests that there are Hepatitis B antibodies in the body, which can immunize against the Hepatitis B virus; if the blood test shows that Hepatitis B core antibody and Hepatitis B e antibody are positive, it suggests that the patient was infected with Hepatitis B virus in the past or has been infected with the Hepatitis B virus at the present. If the patient has been infected with hepatitis B virus, he/she needs to go to the hospital for further examination, combining hepatitis B surface antigen and hepatitis B e antigen to determine whether it is hepatitis B minor triple positive or hepatitis B major triple positive, in addition to checking the DNA of hepatitis B virus, to make it clear that the patient’s blood contains the number of hepatitis B virus. The most important way to prevent Hepatitis B is to receive Hepatitis B vaccine, so that the body can produce Hepatitis B antibodies, but not everyone will produce Hepatitis B antibodies after vaccination. If infected with Hepatitis B, you should go to the hospital immediately, keep optimistic and actively cooperate with the doctor’s treatment.
