1 Answer:

Hello Sandimudap,


Thank you for the question.

HBsAg (Hepatitis B surface antigen) and Anti-HBs (Hepatitis B surface antibody) are 2 examination parameters that can be used in diagnosing Hepatitis B. Hepatitis B itself is a viral infection in the liver parenchyma that can be transmitted through contact between body fluids, especially blood and sexual contact.


HBsAg negative indicates that you have never been infected with Hepatitis B. Whereas, Anti HBs whose levels are more than 10 mIU means you already have immunity against the Hepatitis B virus, it could be due to infection, it could also be because you have ever gotten a Hepatitis B vaccine. Refer to the results of your HBsAg examination which is negative, it is most likely this indicates that you have previously received the Hepatitis B vaccine.


However, please note, that the above examination results need to be confirmed directly with a doctor or specialist in internal medicine who inspects. Therefore, the results of this examination still need to be compared with the results of other examinations conducted.


If it is true that you have already gotten the Hepatitis B vaccine, then do you need to get the vaccine again?


The answer, it may or may not be necessary. Optimally, the hepatitis B vaccine in adults is given in 3 doses. You may need a higher dose if you are considered a high-risk group for hepatitis B infection, for example if you are a health worker.


Hope this helps ...
