Cytomegalovirus PCR


CMV causes mild or subclinical infection in the immunocompetent host. This real-time, quantitative polymerase chain reaction (PCR) assay is used for the regular screening of immunocompromised patients, such as those undergoing bone marrow or solid organ transplants; the early detection of CMV viraemia can allow pre-emptive antiviral therapy. Additionally, the quantitative nature of this assay allows viral load to be monitored during treatment and thus may indicate the presence of antiviral resistant infection, as well as successful treatment. This assay is also used for the detection of congenital CMV infection, often by detection of CMV in urine, as well as respiratory tract infection, hepatitis, colitis, encephalitis and retinitis. The assay includes an internal control for control of both the nucleic extraction and amplification processes.
