Cytomegalovirus IgG and IgM Antibodies Blood Test

Cytomegalovirus (CMV) is a common human virus thought to affect over 50% of the population. It is very common in childhood and most people are unaware that they have got it. CMV is mainly spread through close contact with someone who already has the virus and is usually passed on through body fluids including saliva, blood and urine. Once you are infected, the virus will remain with you for the rest of your life but will usually be inactive. However, it can recur especially in those who have a weakened immune system. Some people may experience flu like symptoms, but usually the virus presents no symptoms.

If a pregnant woman has a current infection, this can be passed on to her unborn baby. Most infected newborns will have no symptoms at birth, but, in some cases, symptoms will appear over the next several years. These include developmental problems and vision or hearing problems.

This test measures levels of IgG and IgM antibodies to rule out or confirm a current or past infection with cytomegalovirus.
