CMV IgG
A CMV IgG test detects IgG antibodies against cytomegalovirus (CMV) in your blood. A positive result typically indicates a past CMV infection and suggests that your immune system has developed long-term immunity to the virus.
What It Measures
This test detects the presence of IgG antibodies directed against cytomegalovirus in your blood. CMV is a common herpesvirus that infects a large proportion of the population. IgG antibodies develop after the initial infection and generally persist for life, indicating past exposure and immune memory.
Why It Matters
While CMV infection is usually harmless in healthy individuals, it can pose risks for immunocompromised individuals and during pregnancy. A primary CMV infection during pregnancy may be associated with complications for the unborn child. Knowing your CMV IgG status helps assess whether you have been previously exposed. Consult a healthcare professional for interpretation.
When to Test
Testing may be recommended during pregnancy planning, for organ transplant recipients, for immunocompromised individuals, or when CMV infection is suspected. Consult a healthcare professional for guidance on whether this test is appropriate for your situation.
Lifestyle Tips
Practise good hand hygiene, particularly after contact with young children or their bodily fluids. If you are pregnant or planning a pregnancy and have not been previously exposed to CMV, take extra precautions such as not sharing utensils with young children. Maintain a healthy immune system through balanced nutrition, regular exercise, and adequate sleep.
Frequently Asked Questions
Is CMV dangerous for healthy adults?
In most healthy adults, CMV infection causes mild or no symptoms and is not considered dangerous. The virus may remain dormant in the body after the initial infection. It can, however, pose risks for individuals with weakened immune systems and during pregnancy. Consult a healthcare professional if you have concerns.
What does a positive CMV IgG result mean for pregnancy?
A positive CMV IgG result before pregnancy generally indicates past infection and existing immunity, which may reduce the risk of a primary infection during pregnancy. However, reactivation or reinfection is still possible in rare cases. Discuss your results with your healthcare provider for personalised guidance.
