Hepatitis B core antibody of 0.012 pei/ml is normal. The normal reference range for Hepatitis B Core Antibody is between 0-0.9 pei/ml and a result of 0.012 pei/ml is normal, or negative. However, the results of the other 4 of the 5 Hepatitis B items should also be taken into consideration to determine if you are infected with the Hepatitis B virus, especially the Hepatitis B Surface Antigen result. A negative Hepatitis B surface antigen indicates that one is not infected by the Hepatitis B virus; a positive surface antigen may indicate Hepatitis B virus infection. A positive viral quantification is indicative of a hepatitis B carrier and regular liver function tests should be performed. Patients with abnormal liver function may need to be treated with hepatoprotective and antiviral therapy, as well as antiviral therapy such as lamivudine and adefovir. Hepatitis B 5 results cannot be analyzed alone, but need to be combined with the 5 results for a comprehensive understanding. If a healthy person has a low level of hepatitis B antibody, it is recommended that he/she be vaccinated against the hepatitis B antibody, and at the same time, he/she should pay attention to maintaining good living habits to avoid infection with the hepatitis B virus.
