Saliva Newborn Screening Test for CMV Found to Be Effective

A saliva-based screening test for cytomegalovirus, or CMV, has been found to be effective in newborns, The New York Times is reporting. CMV, which affects up to one in 150 babies, is part of the herpes family of viruses and can cause permanent hearing loss. In addition, CMV can lead to a "mononucleosis syndrome," which is different from the more common, bacteria-based mononucleosis.

The new screening test does not require a blood draw, is inexpensive, and proved highly accurate in detecting the virus, according to a study just published by The New England Journal of Medicine.

Most children who test positive for CMV do not require any treatment, unless they have a compromised immune system, according to the Mayo Clinic.
