Cytomegalovirus IgG and IgM Antibodies Blood Test

About this test

Cytomegalovirus (CMV) is a common human virus thought to affect oiver 50% of the populations. It is very common in childhood and most people are unaware that they have got it. 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 people with a weakened immune system. 

When first exposed to Cytomegalovirus, a person's immune system is triggered and quickly makes antibodies to fight the virus. 

There are two types of Cytomegalovirus antibodies IgM and IgG:

IgM antibodies are the first to be produced by the body in response to a Cytomegalovirus infection. They are present in most individuals within a week or two after the initial exposure.

IgG antibodies are produced by the body several weeks after the initial CMV infection to provide long-term protection. Levels of IgG rise during the active infection, then stabilize as the CMV infection resolves and the virus becomes inactive.

After a person has been exposed to CMV, they will have some measurable amount of CMV IgG antibody in their blood for the rest of their life.

Our test will confirm a current or previous infection. 

An active Cytomegalovirus infection does gnerally not cause symptoms. However, it may cause prolonged high fever, chills, severe tiredness, a generally ill feeling, headache, and enlarged glands in some people. 

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

Who is this test for?

This test is for people who wish to rule out or confirm a current or past infection with cytomegalovirus as a cause of acute or chronic symptoms.
