Hepatitis B core antibody of 0.01 may be normal or abnormal. This 0.01 is a quantification and needs to be looked at specifically in the normal range behind the test results. If this normal range is less than a value, 0.01 is within the normal range and the test result is negative, which is normal. The corresponding normal range is greater than one value, which can be seen on the clinical test sheet, and the 0.01 in this case is generally positive. A positive hepatitis B core antibody may be abnormal or normal. In the case of abnormality, the previous infection with the hepatitis B virus has turned into a state of chronic infection and is currently a major or minor triplet. If previously infected with the hepatitis B virus, after which the hepatitis B virus was cleared by the body, the hepatitis B core antibody will still survive a positive result at that time. If it is accompanied by a positive hepatitis B surface antibody and not accompanied by a positive hepatitis B surface antigen, it means that it has been cured and can also be considered a normal state.
