Hepatitis B core antibody 2.01 is greater than the normal reference range and is an abnormal result. Hepatitis B core antibody is one of the indicators in the Hepatitis B pentameter, with a normal value of ≤0.9 PEIU/ml. If the quantitative antibody level is 2.01, it exceeds the normal value. If it is core antibody IgM, it indicates that there is a possibility of recent infection with hepatitis B virus, which needs to be evaluated in combination with viral quantification. If it is IgG positive, it indicates a previous infection with the hepatitis B virus. Hepatitis B two halves, in addition to hepatitis B core antibody, also includes hepatitis B surface antigen, hepatitis B surface antibody, hepatitis B e antigen, hepatitis B e antibody, which need to be combined with other indicators to determine whether there is currently an infection with the hepatitis B virus, especially the level of hepatitis B surface antigen. Normally, we should pay attention to the prevention of hepatitis B. If you are a minor or major triple positive, you need to regularly check the quantification of hepatitis B two halves, liver function, quantification of the hepatitis B virus, and liver imaging and other related tests.
