Hepatitis B virus surface antibody positive

There are many hepatitis B patients in life. Some mothers, if they are found to have hepatitis B during pregnancy, will give their children some hepatitis B vaccine after they are born, because hepatitis B is not only contagious but also hereditary. If the hepatitis B disease is more serious, it will cause a lot of harm to the human body. What does a positive hepatitis B virus surface antibody mean?

Those who are resistant to hepatitis B may have hepatitis B antibodies produced after vaccination, or they may have been infected with hepatitis B and recovered, thus developing resistance. A positive test result indicates that the body has become resistant to hepatitis B and will not be infected with hepatitis B again. No special treatment or protection is required.

Hepatitis B surface antibody is a protective antibody. A positive hepatitis B surface antibody indicates that there is antibody in the body and generally you will not be infected by hepatitis B virus and you do not have to worry about infection in daily life. However, you should pay attention to regular check-ups to observe whether the antibody exists and its strength, and continue to get the hepatitis B vaccine in time when the antibody is weak to ensure the antibody titer, thereby effectively resisting the hepatitis B virus and better maintaining human health.

Generally speaking, if the hepatitis B two-pair-and-a-half test is positive, there are three situations:

1. If the second item of the single hepatitis B two-pair half test is positive, it means that the hepatitis B vaccine is successful;

2. If both the second and fifth items of the two-pair hepatitis B test are positive, it means that the body has been naturally infected (including latent infection and overt infection) with hepatitis B virus (HBV) and an immune response has occurred. The hepatitis B virus has been cleared and the body has acquired specific immunity against the re-invasion of the hepatitis B virus.

3. The first and second items of the two-pair hepatitis B test are both positive. This is rare and may be related to the following factors: (1) infection with different hepatitis B virus subtypes; (2) infection with hepatitis B virus with S gene mutations; (3) low immune function, and anti-HBs cannot clear HBsAg;

Two possibilities

1. Those who have been infected with hepatitis B virus in the past but have protective antibodies do not rule out the possibility of contagion.

2. Have been vaccinated with hepatitis B vaccine and produced corresponding protective antibodies - surface antibodies, but have been in contact with hepatitis B patients for a long time and produced E antibodies. Don't worry, you don't have hepatitis B! Normal healthy person. Guidance: If the test result is positive and you have not received the hepatitis B vaccine, it means that your immunity is acquired through long-term contact with the infection in your life. Hello, you can burn incense and worship Buddha. However, the presence of core antibodies indicates the existence of core antigen, but it is also possible that the core antigen no longer exists. Therefore, it cannot be ruled out that you are contagious, but you yourself cannot get hepatitis B.
