Hepatitis B core antibody positivity and DNA negativity indicate previous or ongoing hepatitis B infection, but the virus is not actively replicating and is lowly contagious. Hepatitis B core antibodies are a sign of previous or ongoing infection. The core antibody IGM is a sign of recent infection or viral replication, and the core antibody IgG is produced after infection. Hepatitis B DNA, the deoxyribonucleic acid of the hepatitis B virus. Hepatitis B DNA is the most direct, specific and sensitive indicator of hepatitis B infection. Hepatitis B DNA indicates that hepatitis B is replicating and infectious. The higher the Hepatitis B DNA, the greater the replication of the virus and the more infectious it is. Hepatitis B DNA is negative, showing that the virus is not replicating and is weakly infectious. Hepatitis B core antibody positive DNA negative indicates previous or ongoing infection with hepatitis B, but the virus is not actively replicating, low infectiousness. The highest complete liver function tests, liver ultrasound, etc., there is no abnormality can be regularly rechecked.
