A positive Hepatitis B Virus Core Antibody test indicates a previous infection with the Hepatitis B Virus, but is not definitively normal and should be referred to the results of the other Hepatitis B Penta tests. Under normal circumstances, the hepatitis B core antibody test is negative, while a positive test means that the patient has been infected with the hepatitis B virus in the past. It is not possible to determine whether the test is normal or not by only one result, and it is necessary to combine the results with other indicators to make a comprehensive diagnosis. If Hepatitis B core antibody is positive, Hepatitis B surface antigen and Hepatitis B e antigen are positive, it means that the patient is suffering from acute or chronic Hepatitis B, and the virus is actively replicating and highly infectious, which is not normal. Positive hepatitis B core antibody, hepatitis B e antibody and hepatitis B surface antigen means acute and chronic hepatitis B, but the infectiousness is weak and abnormal. However, positive hepatitis B core antibody, and hepatitis B surface antibody, hepatitis B e antigen, hepatitis B e antibody, hepatitis B core antibody is negative, indicating that had been infected with hepatitis B, but the virus has been completely cleared, has been cured, is normal. It is recommended that people with positive core antibody against hepatitis B virus should consult their doctors in time and make a comprehensive diagnosis by combining the results of other tests, so as to choose the appropriate diagnosis and treatment plan according to their conditions and to promote the recovery of health of the organism.
