Clinical Significance
In patients who are immunocompromised, CMV may cause disseminated, severe disease. CMV is also the most common cause of congenital viral infection in humans. Quantitative PCR methods may be useful in monitoring CMV replication in immunosuppressed patients. This is a quantitative molecular test, with a linear range of 34.5-10,000,000 IU/mL (1.54-7.00 log IU/mL).
