Question
Hello doctor,
Blood test results for hepatitis B are as follows: HBsAg negative 0.41, anti Hbs 29.9, total anti HBc positive 0.51. So the doctor asked me if a woman with a negative HBsAg 0.41 has any effect? Do I have hepatitis B? I thank the doctor.

Hello,
With the question “What is the effect of female HBsAg negative 0.41? ”, the doctor would like to answer as follows:
Your test result is HBsAg negative. So now, you are not infected with hepatitis B. Your anti-HBs result is 29.9, which means you are immune to hepatitis B virus, although this antibody level is still low. The total anti-HBc result is positive 0.51, which means you have ever been infected with hepatitis B. The above results show that you have been infected with hepatitis B but have recovered and your body has started to have immunity to the hepatitis B virus. You need to be tested periodically, to see if the amount of antibodies to the hepatitis B virus increases or decreases over time.
If you still have questions about women with HBsAg negative 0.41, you can go to a hospital under Vinmec Health System for further testing and advice. Thank you for trusting and sending questions to Vinmec. Wishing you lots of health.
Best regards!
