Can hbsag be nagitive

Yes, HBsAg (Hepatitis B surface antigen) can be negative, indicating that a person is not currently infected with the hepatitis B virus. A negative HBsAg test result may suggest either recovery from a past infection or that the person has never been infected. However, for a comprehensive understanding of hepatitis B status, additional tests such as anti-HBs and anti-HBc should also be considered.
