  • HBsAg (hepatitis B surface antigen) is the first serologic marker to appear in a new acute infection, which can be detected as early as 1 week and as late as 9 weeks, with an average of one month after exposure to the hepatitis B virus (HBV). 

 

- HBsAg is detectable for a variable amount of time, along with the HBV DNA, though about 50% of persons will test HBsAg and HBV DNA negative 7 weeks after symptoms.

 

- All persons who spontaneously recover from an infection will test negative for HBsAg and negative for HBV DNA about 15 weeks after the appearance of symptoms.
