Cystic Fibrosis

Abnormal Newborn Screening Results and Additional Testing

If your baby’s newborn screening results are abnormal, your baby will need to have another test.  Not every abnormal result means your baby has a disorder.  It is important to have quick follow-up testing.  Without treatment, Cystic Fibrosis can result in harmful effects soon after birth. 
The Utah Newborn Screening Program will contact you and your child’s pediatrician for additional testing.  This may include having a “Sweat Test” performed at the Primary Children’s Hospital Outpatient Lab.
The Cystic Fibrosis Clinic at Primary Children’s Hospital cares for babies diagnosed with Cystic Fibrosis.

About Cystic Fibrosis

Cystic Fibrosis is a disorder of the mucous glands. Children affected by Cystic Fibrosis produce excess mucus that is abnormally thick and sticky.  Mucus is important to the lungs, digestive system, reproductive system, and other organs and tissues.

If untreated, Cystic Fibrosis can cause lifelong health problems that can lead to early death.  However, if Cystic Fibrosis is detected early and proper treatment is begun, children can have decreased symptoms and live longer healthier lives.


The frequency of Cystic Fibrosis varies by ethnicity.  In the United States, approximately 1 in 3,500 Caucasian babies, 1 in 7,000 Hispanic babies, and 1 in 17,000 African American babies are affected by Cystic Fibrosis.
