Cytomegalovirus Antibodies (IgG, IgM)

What this laboratory test evaluates

DetailsCytomegalovirus Antibodies (IgG, IgM) – Intrauterine or congenital CMV infections occur in 0.5 to 2.2% of all live births. Symptomatic congenital infections usually occur in infants born to non-immune mothers who have primary infections during pregnancy. Latency and reactivation of CMV influence the interpretation of serological results. A single positive CMV IgG result is and indication of present or past infection. The presence of CMV IgM suggests a recent CMV exposure but does not differentiate between primary infection and reactivation.

What type of sample is required for this test?1.5 mL serum
