A high level of anti-hepatitis B surface antibody indicates the presence of antibodies to the hepatitis B virus in the body, while a high level of anti-hepatitis B core antibody, i.e. core antibody to the hepatitis B virus, indicates that the patient has been infected with the hepatitis B virus or is currently infected with the hepatitis B virus, or there may be false positives. There are two possible scenarios that these two items are high at the same time: the first one is that the patient has been infected with hepatitis B virus and has produced antibodies; the second one is that the patient has not been infected with hepatitis B virus and has been vaccinated against hepatitis B virus. 1. The patient has been infected with hepatitis B virus: the patient has been infected with hepatitis B vaccine, but under the action of the body’s immune system, the patient has produced antibodies, which suggests that the body has already had a protective effect and is not contagious, so there is no need for treatment. 2. The patient has not been infected with hepatitis B virus: if the patient is injected with hepatitis B vaccine, it will also cause the patient to have high hepatitis B surface antibody, which can protect the body from being infected by hepatitis B virus, so the core antibody of hepatitis B virus may appear false positive, so the patient may not have been infected with hepatitis B virus. Hepatitis B two-half test suggests that the results of these two tests are high, you should consult a regular hospital in time, and if necessary, test for hepatitis B virus DNA content.
