what is the window period for hepatatis b
Response from Dr. McGovern
The window period specifically refers to the time after HBsAg has disappeared but before HBsAb has appeared. During this time, an IgM antibody may be the only positive marker of infection.
In acute (new) HBV infection, the incubation period is generally about one to four months after exposure.
