Hello doctor,
Recently, I had a blood test that was positive for HBsAg 6.2 s/co, but HBsAb was negative, I tested positive for HBsAg, what does HBsAb mean ? Is your condition acute or chronic hepatitis B? Do I need any more tests to confirm? Thank you doctor.

Hi,
With the question “What does HBsAg test positive, HBsAb negative mean? , the doctor would like to answer as follows:
With the HBsAg test result 6.2 s/co, your negative HbsAb and HBeAg cannot confirm whether you have acute or chronic hepatitis. Low level positive HbsAg (6.2 s/co), does not confirm whether you have hepatitis B infection or not? The results only confirm that you do not have antibodies to the hepatitis B virus. You need to do other tests such as: HBsAg confirmed, HBc IgM, HBc total to confirm whether or not you are infected with the HBV virus and if infected, at what stage.
If you still have questions about a positive HBsAg test, 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!
