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.

Method Description

The Simplexa Congenital CMV (cytomegalovirus) Direct assay is a real-time polymerase chain reaction system that enables the direct amplification and detection of CMV DNA from either saliva swab or urine specimens without nucleic acid extraction. The system consists of the Simplexa Congenital CMV Direct Reaction Mix, the LIAISON MDX (with LIAISON MDX Studio Software), the direct amplification disc, and associated accessories.

 

In the Simplexa Congenital CMV Direct assay, bifunctional fluorescent probe-primers are used together with corresponding reverse primers to amplify CMV DNA. A well-conserved region of the CMV UL83 gene is targeted to identify CMV DNA. An internal control is used to detect PCR failure and/or inhibition.(Package insert: Simplexa Congenital CMV Direct.
