Really worried...please answer

I had a risky sexual exposure 104 days back.
I got my HIV antibody test done after completing the window period and it turned out to be negative.
I was advised to get a Hepatatis B test done because of my high risk exposure.
I got a HBSAg test (using Chemiluminsence method) done after 104 days and the report showed non-reactive with a reading of 0.05. I also think I didn't complete the dosage of the 3 vaccinations to be done for Hepatitis B)
1) Is my test for Hepatitis B conclusive and final or do I need further testing and if yes, when do I need to get tested next??
2) What is the window period for Heptatis B test using the test I mentioned above??
I will greatly appreciate you responses.
Thanks!!

Hello and hope you are doing well.

Diagnosis of hepatitis B infection is based on the raised levels of HBsAg of IgM. If this is negative, you are unlikely to have an acute infection. If you want to see your immunity status to hepatitis B post vaccination have an Anti Hbs done. Anti Hbs levels above 10 IU/L are considered to be protective.

Hope this helped and do keep us posted.
