Introduction
HBsAg is the abbreviation for hepatitis B surface antigen. A positive test result usually indicates infection with the hepatitis B virus and suggests that the person is infectious. The hepatitis B virus is primarily transmitted through blood, sexual contact, and mother-to-child transmission. A positive HBsAg result confirms infection with the hepatitis B virus.

The hepatitis B virus is primarily transmitted through blood, sexual contact, and mother-to-child transmission. A positive HBsAg result confirms infection with the hepatitis B virus, but it does not necessarily mean that the individual will develop hepatitis B disease. Most people's immune systems can clear the virus naturally; only a minority will progress to chronic hepatitis B, requiring long-term treatment and management. Under a doctor’s guidance, antiviral medications such as lamivudine tablets or tenofovir alafenamide fumarate tablets may be used for treatment.
If the HBsAg test result is positive, it is recommended to promptly consult a healthcare professional for further evaluation and diagnosis. It is also important to recognize that hepatitis B virus infection is contagious, and appropriate preventive measures should be taken to avoid transmitting the virus to others. For example, avoid sharing personal hygiene items such as toothbrushes and razors, and practice safe sex.
