This test is only orderable for patients less than 22 days old.

  
  • 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.
