Hepatitis B surface antibody is a substance that has a protective effect on the body, and a value greater than 10 mIU/mL usually indicates that the vaccine is working after the hepatitis B vaccination. Generally, the higher the test value, the stronger the protective effect of the antibody on the body. Newborns are at high risk for hepatitis B infection, so newborns need the first dose of hepatitis B vaccine as soon as possible, followed by the second and third doses of hepatitis B vaccine one month and six months later, respectively. The level of hepatitis B antibodies in the body decreases with age. For those who are at high risk of contracting the hepatitis B virus, a hepatitis B surface antibody test can be performed at regular intervals (e.g., every 3-5 years) for hepatitis B prevention. In addition, the hepatitis B surface antibody value can also represent the effectiveness of hepatitis B treatment, and a value greater than 10 mIU/mL can also indicate the effectiveness of hepatitis B treatment. However, patients with hepatitis B need to be reviewed regularly to avoid a decrease in antibody levels or an aggravation of the disease. Patients with a clear diagnosis of hepatitis B need to adjust their emotions, maintain a good work schedule, and get comprehensive nutrition. However, if a patient has a hepatitis B surface antibody of more than 10 mIU/mL and other abnormal or positive indicators, further examination is needed to consider whether other conditions are present.
