Reference Range

CMV DNA, QN PCR	Not Detected (IU/mL)
CMV DNA, QN PCR	Not Detected (Log IU/mL)

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).
