Hepatitis B surface antibody positive

When it comes to liver disease, many friends will think of hepatitis B. This is not surprising. You should know that my country is a major country with hepatitis B. The number of people suffering from hepatitis B in my country has exceeded 100 million. A survey shows that one in ten people is a hepatitis B patient, and hepatitis B is also contagious and hereditary. It is precisely because of this that many friends are very afraid of hepatitis B and worry that they will contract the disease.

However, many friends will find that their hepatitis B surface antibody is positive when undergoing liver function tests. At this time, many friends will be very anxious, thinking that they have hepatitis B. So, is this true? What exactly is going on with positive hepatitis B surface antibody?

Hepatitis B surface antibody is an immune and protective antibody against the hepatitis B virus. A positive hepatitis B surface active antibody test indicates that the person has been infected with the hepatitis B virus in the past but the virus has been eliminated, or that the person has been vaccinated with the hepatitis B vaccine and has produced protective antibodies. The higher the hepatitis B surface antibody titer in the serum, the stronger the protection. However, there are a small number of people who are positive for hepatitis B surface antibodies and yet develop hepatitis B. This may be due to infection with a different subtype or a mutation of the hepatitis B virus.

The positive appearance of hepatitis B surface antibody means that among the five hepatitis B serum markers, the antigen is a component of the virus itself, while the antibody is a product of the body's immune response, and their clinical significance is different. Hepatitis B surface antibody is a protective antibody that often appears positive in the late stage of infection recovery, at which time the hepatitis B surface antigen has turned negative for at least one month. Hepatitis B surface antibodies reach a peak in June-December, then gradually decline and turn negative within 10 years (sometimes very quickly).

Many people only know that a “+” in the five hepatitis B tests is not good, and therefore they mistakenly believe that a positive hepatitis B surface antibody test is also a bad thing. In fact, this is not the case. Hepatitis B surface antibodies are protective antibodies of the human body. They are not only beneficial to the human body, but also can protect the human body from being invaded by the hepatitis B virus! Therefore, a positive hepatitis B surface antibody is a good thing.

After reading the introduction in this article, I believe you must know what hepatitis B surface antibody positivity means, and I believe you will feel very relieved, because hepatitis B surface antibody positivity not only means that you do not have hepatitis B, but also means that you have a certain resistance to the hepatitis B virus, so you no longer have to worry about contracting hepatitis B.
