But if you just want to know if it's type 1 or type 2, the treatment is the same either way, so there is no point. ...Read more

However, if one was exposed recently, and got a new infection, he could be in the brief window period, if the HBcAb test was for IgG only (thus missing HBcAb IgM). His Dr. Can explain. ...Read more
