Cytomegalovirus (CMV) Saliva Real-Time PCR
For the detection of CMV in Saliva. Congenital CMV infection can be diagnosed by testing a newborn baby’s saliva, urine, or blood by CMV PCR. However, of the three specimen types that are recommended, only saliva is simple, noninvasive and easy to collect. Specimens must be collected for testing within 21 days after the baby is born in order to confirm a diagnosis of congenital CMV infection. Specimen collection should be performed at least 90 minutes (and preferably 120 minutes) post-breastfeeding.
Extraction of CMV DNA from saliva followed by amplification and detection using real-time, PCR. An internal control is added to ensure the extraction was performed correctly and the PCR reaction was not inhibited. Viracor's assay design includes multiple targets to account for viral mutations, which significantly reduces the chance of false negative results. This test has not been cleared or approved for diagnostic use by the U.S. Food and Drug Administration.
The primers and probes used in this assay are specific for known CMV strains based on similarity search algorithms. Additionally, no cross reactivity was detected when tested against adenoviruses, BKV, EBV, HSV-1, HSV-2, HHV-6 variant A, HHV-6 variant B, HHV-7, HHV-8, JCV, parvovirus B19, SV-40, and VZV.
