Your Hepatitis B Antibody Test Results and Immunity

Hepatitis antibodies

In your school health check, the results indicate that the Hepatitis B surface antigen (HBsAg) is negative at 0.084, and the Hepatitis B surface antibody (anti-HBs) is positive at 1.067.
This means that you have antibodies against Hepatitis B, which suggests that you have immunity to the virus.

Having a positive anti-HBs result typically indicates that you are either vaccinated against Hepatitis B or have recovered from a past infection, and you are unlikely to contract the virus in the future.

As for further testing, it may not be necessary unless your healthcare provider recommends it based on your medical history or other risk factors.
However, it's always a good idea to discuss your results with a healthcare professional for personalized advice.
Thank you!

Your hepatitis B antibody test is positive, indicating that you have been infected with hepatitis B in the past.
Your body has produced antibodies against hepatitis B, and you will not be reinfected with hepatitis B in the future.

More Info

Based on your Hepatitis B test results, you have a negative Hepatitis B surface antigen (HBsAg) and a positive Hepatitis B surface antibody (anti-HBs). Specifically, your HBsAg result of 0.084 indicates that you do not currently have an active Hepatitis B infection, as a value below 1.0 is considered negative. On the other hand, your anti-HBs result of 1.067 indicates that you have developed antibodies against the Hepatitis B virus, which is a sign of immunity.

To clarify, the presence of anti-HBs means that your body has either successfully cleared a past Hepatitis B infection or that you have been vaccinated against the virus. Since you mentioned that you had received the Hepatitis B vaccine in the past, it is likely that your positive anti-HBs result is due to the vaccination. This means you have developed immunity to Hepatitis B, and you are protected against future infections.

In terms of your immunity, having a positive anti-HBs result generally indicates that you are at low risk for contracting Hepatitis B. You do not need to undergo further testing for Hepatitis B unless you have specific concerns or symptoms that warrant additional investigation. However, it is important to monitor your antibody levels over time, especially if you have any risk factors for Hepatitis B exposure.

Regarding the need for booster vaccinations, the Centers for Disease Control and Prevention (CDC) recommends that individuals who have received the Hepatitis B vaccine should have their anti-HBs levels checked if they are at high risk for exposure to the virus or if they have certain medical conditions. If your anti-HBs levels fall below 10 mIU/mL, it may be advisable to receive a booster dose of the vaccine to ensure continued immunity.

In summary, your test results indicate that you have immunity to Hepatitis B, and you are not at risk of contracting the virus. It is always a good practice to discuss your results with your healthcare provider, who can provide personalized recommendations based on your health history and risk factors. Regular check-ups and monitoring of your health status are essential to maintain your overall well-being.
