A member asked:

When is the soonest that a hepatitis b surface antigen test can detect the virus after exposure?

A doctor has provided 1 answer

Hep B surface Ag: It can take 30 to 150 days to develop symptoms of hepatitis B after you become infected. Hepatitis B surface antigens can be found in your blood within 12 weeks after the infection starts. They are one of the earliest signs of a hepatitis B infection.
