Clinical Information

Cytomegalovirus (CMV) is a double-stranded DNA virus of the Herpesviridae family. CMV is transmitted through direct contact from a variety of infected body fluids, as well as through sexual contact, organ transplantation, and intrauterine transmission during pregnancy.(1) CMV infection may be asymptomatic but can cause a wide range of symptoms, especially in immunocompromised individuals. Congenitally acquired CMV (cCMV) may lead to long-term sequelae, including visual and hearing impairments, and cognitive and motor deficits.(2) Current recommendations indicate testing urine and saliva swabs for cCMV using a nucleic acid amplification detection method.(3)

Reference Values

Negative

Interpretation

A positive result indicates the presence of cytomegalovirus (CMV) DNA in the patient sample.

 

A negative result indicates the absence of CMV DNA in the patient sample.

 

An invalid result indicates inability to conclusively determine presence or absence of CMV DNA in the patient sample.
