Overview
Laboratory Findings
The following laboratory investigations are useful for the diagnosis of cytomegalovirus infection:
Serological Tests
- Serological tests are not useful for the diagnosis of cytomegalovirus infection, however absence of CMV IgG excludes the presence of infection.
Polymerase Chain Reaction
- In patients with cytomegalovirus retinitis CMV DNA is detected in the vitreous in majority of patients.
- PCR for demonstration of CMV DNA is useful for the diagnosis of retinitis and neurologic disease.
- PCR of blood for demonstration of viremia is not useful for diagnosis of cytomegalovirus end organ disease as a negative result is not consistent with the absence of disease.
