Hepatitis B antibody titer is less than 10. Antibodies greater than 8 are positive protective antibodies, and those less than 8 are negative, so there is no protection! Therefore, it can be protected below 10, but the injection of hepatitis B vaccine should be strengthened immediately! Otherwise it will disappear soon.
The titer of hepatitis B surface antibody is less than 10 10miu/ml, which is negative.
Guiding opinions:
People whose antibody titer is lower than 10 need to be strengthened and given three injections in stages. 30 days after the first injection, the second injection can be carried out, and the third injection can be carried out on 180 days.
Anti-HBs This is an antibody produced after the surface antigen of hepatitis B virus (HBsAg) stimulates the human immune system. It is a protective antibody, also known as neutralizing antibody. It can neutralize the infectivity of hepatitis B virus and protect human body from the second attack of hepatitis B virus.
Anti-HBS positive indicates at least three problems:
Analysis chart of hepatitis B virus (1) Patients with hepatitis B have reached the recovery stage, and will bid farewell to hepatitis B virus infection from now on;
(2) I have been infected with hepatitis B virus in the past, and I may have been infected with hepatitis B disease or unconsciously, but now the virus has been cleared and I am immune to hepatitis B. Even if there is hepatitis B virus invading the body, I am still safe and sound;
(3) It is a sign of successful immunization with hepatitis B vaccine. Of course, it will not be infected with hepatitis B virus again.
Among the three brothers of hepatitis B antibody, anti-HBS is the most special, which is contrary to hepatitis B antigen (HBsAg, HBeAg, HBCAg). If it is positive, the antigen will be negative. Only in very special circumstances, anti-HBS and HBsAg appear at the same time.
How long can hepatitis B antibody last? Hepatitis B antibody generally lasts for 3-5 years. However, the situation of each vaccinator is different. Some people have higher antibody levels and last longer after being vaccinated with hepatitis B vaccine. However, after some people are vaccinated with hepatitis B vaccine, the antibody level is low and the duration is short.
When the antibody of hepatitis B in the body disappears or is too low, the hepatitis B vaccine should be replanted. The titer of hepatitis B surface antibody should be determined before multiple cropping. The higher the titer of HBsAg in serum, the stronger the protective effect and the longer the duration.
When the antibody titer of hepatitis B surface is less than or equal to 10 IU/ml, it should be inoculated within half a year, and the antibody titer is greater than 10 IU/ml, and it can be replanted within 6 years. Liver disease experts suggest that it is better to strengthen the injection of hepatitis B vaccine 1 time within 3 years after immunization.
When hepatitis B virus invades the human body, it will stimulate the immune system to produce an immune response, and B cells in the immune system in the body will secrete a special human immunoglobulin, namely surface antibody, which can specifically bind with hepatitis B surface antigen, and then clean up the hepatitis B virus together with other immune abilities in the body, while protecting the human body from hepatitis B virus infection. With surface antibodies, it is proved that people already have immunity. If the positive result of hepatitis B surface antibody is detected, it means that they will no longer be infected with hepatitis B. ..
