    Normal results for a hepatitis A test are negative. This means that there were no immunoglobulin M (IgM) antibodies in the blood. The IgM antibody shows up 3–4 weeksafter exposure to the virus. The antibody peaks one month after symptoms appear and becomes difficult to detect after 3–4 months. Positive test results can indicate someone has or previ...

    Normal results for a hepatitis B test are negative, which means that there were no hepatitis B antigens (HBsAg) in the blood. Doctors typically interpret HBsAg in the blood as an acute or chronic infection. This typically occurs 2­–6 weeksafter exposure to the virus. The antigen peaks shortly before or after symptoms begin and is difficult to detec...

    Normal results for hepatitis C are negative, which indicates that there were no immunoglobulin G antibodies in the blood. These antibodies typically peak after 6­–12 monthsof exposure to the virus.
