Hepatitis B Pentathlon includes Hepatitis B Surface Antigen, Hepatitis B Surface Antibody, Hepatitis B e Antigen, Hepatitis B e Antibody, and Hepatitis B Core Antibody. Hepatitis B Pentathlon is a hepatitis B test that determines whether a patient is infected with the hepatitis B virus, whether there are protective antibodies against hepatitis B in the body, and how contagious the virus is. A fully negative Hepatitis B Penta test result indicates that the patient is normal and not infected. As most people receive hepatitis B vaccination, the second item, i.e. surface antibody, is positive, while the other four items are negative, which indicates that the body has produced antibodies to fight against hepatitis B antigens, which can effectively prevent hepatitis B virus infection. However, with the prolongation of time, the level of antibodies in the body may gradually decline, and can be regularly rechecked, if the second item is negative, it is recommended to timely replenish the vaccine. If the surface antigen, e antigen and core antibody are positive, it means that it is triple sun, which is highly infectious; if the surface antigen, e antibody and core antibody are positive, it means that it is triple sun, which is weakly infectious. If you are only checking the hepatitis B five items, you don’t need to fast. If you need to do other related tests at the same time, you need to fasting, so as not to affect the test results.
