What Is a Hepatitis B Titer?

Hepatitis B antibodies refer to hepatitis B protective antibodies, that is, hepatitis B surface antibodies, and hepatitis B antibody titers refer to the concentration of hepatitis B surface antibodies. When the hepatitis B surface antibody concentration reaches a certain level, the human body can be more effectively protected from the invasion of hepatitis B virus.

Hepatitis B antibodies refer to hepatitis B protective antibodies, that is, hepatitis B surface antibodies, while hepatitis B antibody titers refer to

There are generally two ways to produce hepatitis B surface antibodies: 1. Once infected with hepatitis B virus, but because of its strong immune function, the hepatitis B virus was eliminated and hepatitis B surface antibodies were produced. 2, produced after injection of hepatitis B vaccine. Therefore, after the hepatitis B vaccine is completed, the hepatitis B antibody titer is mainly checked by its concentration. The greater the value of the hepatitis B antibody titer, the stronger the ability of the patient to resist the hepatitis B virus.

Normal antibody titer

In general, the normal value of hepatitis B antibody titer is 10mIU / ml. When the hepatitis B antibody titer is greater than this value, the hepatitis B surface antibody can effectively protect the human body. Once the hepatitis B antibody titer is less than this value, the protective ability of the hepatitis B surface antibody is weakened. At this time, once the patient is exposed to the blood containing the hepatitis B virus, or is in close contact with the patient carrying the hepatitis B virus, he may be infected with the hepatitis B virus. At this time, it is better to go to the hospital to inject one

Antibody titer considerations

The hepatitis B antibody titer will gradually decrease with the passage of time. The maintenance time of hepatitis B antibody is determined by the patient's own immunity. Most patients can maintain the hepatitis B antibody for up to 5 years, but some patients It can only be maintained for 2-3 years, so in order to avoid infection with hepatitis B, patients are better to go to the hospital for a test after 2-3 years.

The highest titer of hepatitis B antibody is only 10 100mIU / ml, it is best to repeat the test after 6 months;

When the highest titer of hepatitis B antibody is 101 1000mIU / ml, the test should be repeated within 1 2 years after the first injection.

Hepatitis B antibody titer can be obtained by quantitative detection of hepatitis B markers, so how to look at the hepatitis B antibody titer? The titer of the hepatitis B antibody can be displayed on the test sheet, and the titer can be judged by checking the titer. The minimum value that can effectively protect the human body from virus infection is 10mIU / mL. When the test results show that the hepatitis B antibody titer is less than 10mIU / mL, it indicates that the titer is relatively low, and hepatitis B vaccine needs to be injected. If it is greater than 10mIU / mL, it can effectively protect the human body from infection.

When injected with hepatitis B vaccine, most people will produce hepatitis B antibodies and the titer is relatively high, but some people will produce lower titers or even no antibodies. So after getting the hepatitis B vaccine, don't be ill, go to the hospital to check the titer of the hepatitis B antibody. However, the titer will decrease over time. Experts suggest that the hepatitis B vaccine should be injected at the hospital within 3-5 years after injection, especially for newborns.

After a person has been injected with hepatitis B vaccine, the amount of antibodies in the body will gradually decrease over time, and the protective ability of the body will also decline. The greater the hepatitis B antibody titer, the stronger the body's protective ability. Therefore, the examination of the hepatitis B surface antibody titer can clearly know the body's antibody content and whether a booster injection of the hepatitis B vaccine is needed, which is of great significance for the prevention of hepatitis B. In addition, some people who have received the hepatitis B vaccine have little or no antibody titers. At this time, it is necessary to test the hepatitis B antibody titer.

What does the hepatitis B antibody do?

1. Can inhibit the growth and reproduction of pathogens.

2, can prevent viruses or germs from approaching human cells.

3. Can neutralize the virus.

4, can neutralize the toxins of germs.

5, can neutralize the toxins of germs.
