Cytomegalovirus (CMV) IgG Antibody Test

Cytomegalovirus, commonly known as CMV, is a widespread virus that infects people of all ages. In healthy individuals, CMV often causes mild symptoms or no symptoms at all, which means many people never realize they have been infected. Once exposed, the virus remains in the body in a dormant state and can reactivate later, particularly when the immune system is weakened.

This CMV IgG blood test detects Immunoglobulin G antibodies to cytomegalovirus. IgG antibodies develop after a past infection and typically remain in the body for life. A positive IgG result indicates previous exposure and suggests some level of immune memory. A negative result indicates that you have not been previously exposed and may be at risk for primary infection.

CMV testing is especially important for individuals who are pregnant or planning pregnancy. A primary CMV infection during pregnancy can increase the risk of congenital CMV, which may lead to complications such as hearing loss, vision impairment, developmental delays, or other long term health issues in the baby. Understanding your immune status allows you and your healthcare provider to take appropriate precautions.

This test is also valuable for individuals with weakened immune systems, including transplant recipients, people living with HIV, and those undergoing immunosuppressive therapy. In these populations, CMV reactivation or new infection can lead to serious illness. Knowing your CMV IgG status helps guide monitoring and preventive strategies.

What Is Included In This Test?

This test includes:

• Measurement of Cytomegalovirus IgG antibodies in the blood
• Laboratory analysis to determine prior CMV exposure
• Clear numerical results for clinical interpretation

This is an IgG antibody test and identifies past exposure. It does not diagnose a current active infection. Additional testing, such as CMV IgM or other diagnostic evaluation, may be recommended if recent infection is suspected.

Why Does This Test Matter?

CMV is extremely common, yet most people do not know their immune status. For pregnant individuals, transplant recipients, and those with weakened immune systems, understanding prior exposure is critical.

A positive IgG result may provide reassurance of past exposure and immune memory. A negative result identifies susceptibility, allowing you to take preventive precautions if needed.

Early awareness of your CMV status supports better pregnancy planning, safer transplant preparation, and informed healthcare decisions.

Knowing your immune status empowers you to protect your health and reduce potential risks associated with CMV infection.

Who Should Consider This Test?

You may consider this test if you:

• Are you pregnant or planning to become pregnant
• Have been exposed to someone diagnosed with CMV
• Work in healthcare, childcare, or other high-exposure environments
• Have a weakened immune system
• Are preparing for an organ transplant
• Want to confirm prior CMV exposure and immune status
