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.
This test is only orderable for patients less than 22 days old.
Specimen collection should be performed at least 90 minutes (and preferably 120 minutes) post-breastfeeding.
