The minus sign in the Hepatitis B Penta test chart means a negative result. Hepatitis B 5 refers to the five indicators of Hepatitis B: Surface Antigen, Surface Antibody, E Antigen, E Antibody and Core Antibody, which are used to test whether the body carries the Hepatitis B virus or not, and whether there is any antibody against the Hepatitis B virus in the body or not. If there is a minus sign on the results chart, it means that you do not have hepatitis B and you do not have antibodies to the hepatitis B virus. Even if you do not have Hepatitis B, it is recommended that you go to the hospital to get a Hepatitis B vaccination for safety reasons, which can increase your antibodies and reduce the possibility of contracting Hepatitis B. When the results of Hepatitis B 5 are abnormal, you should go to the doctor in time to complete the relevant examinations, make a clear diagnosis and receive systematic treatment under the doctor’s guidance.
