| Additional information | Clinical Significance: CMV infections are common and usually asymptomatic.In patients who are immunocompromised, CMV may cause disseminated, severe disease. CMV may cause birth defects in a minority of infected newborns. DNA methods provide the highest sensitivity and specificity of any method. For detection of CMV in congenital infection, qualitative CMV culture of urine has adequate sensitivity and better specificity than PCR, which can be too sensitive and pick up very low levels of virus. While CMV PCR on urine from immunocompromised patients has a fairly low specificity for disease, there is some literature describing utility of quantitative CMV PCR on urine for following renal transplant patients. |
