Cytomegalovirus, or CMV is a virus of the herpes family. It is thought that it is transmitted through bodily fluids, and the symptoms include fever, sore throat and swollen lymph nodes. The virus can cause birth defects and pregnancy complications in pregnant women. The virus can also be very dangerous for immunocompromised individuals. Many organs can become inflamed and damaged, including the liver, the retina, and the colon (large intestine.)
A few weeks after being initially infected with CMV, the immune system produces an antibody called IgG.
What might a low result mean?
A negative CMV Ag ab (IgG) result indicates that you have not been previously exposed to CMV.
What might a high result mean?
A positive CMV Ag ab (IgG) result indicates a previous CMV infection.
