HBsAg positive meaning

Explanation:
HBsAg positivity means there is an active hepatitis B virus infection in the person. The surface antigen being present shows the virus is circulating and the person is infectious. This can be part of an acute infection or a chronic infection; if HBsAg persists for more than about six months, the infection is considered chronic. It does not indicate latent infection. In a resolved infection, HBsAg would be negative and anti-HBs would be positive (often with anti-HBc as well).
