Newborn Screening

Identifying Infants with Certain Genetic Conditions

Newborn screening is a public health activity aimed at early identification of infants affected with certain genetic or metabolic

conditions.  Through laboratory testing at birth, Illinois screens for several endocrine, hemoglobin and metabolic disorders. Early

diagnosis and treatment can reduce morbidity, premature death, mental retardation and other development disabilities. The list

of conditions included in the screening has greatly expanded over the years, resulting in earlier detection and prevention of

complications in many previously undetected disorders. A specimen will be collected at least 24-hours after birth. If an

abnormality is detected with the screening (i.e. elevated or positive results, or an unsatisfactory specimen) and neither the Illinois

Department of Public nor the physician are able to locate the family, then the Will County Health Department is notified.  Further

attempts to reach the family will be made by a nurse, either via telephone or by an attempted home visit. The nurse can then

inform the family of the importance of a repeat screening or the need for further diagnostic testing.  If there is a definitive

diagnosis, the RN can provide referrals and educational material to the family.


In addition, newborns are also screened at birth for hearing. There are many reasons why an infant might fail the first hearing

screening at the hospital, but it is important that a follow-up test be performed in order to rule-out a definite hearing loss. Early

recognition and treatment of confirmed hearing loss is essential to prevent future complications.


The Will County Health Department is notified by the Illinois Department of Public Health of infants who have failed their

Newborn Hearing Screening and need to follow-up with repeat or further testing. A nurse will attempt to contact the family either

by phone or home visit to make sure the family has all the information and referrals it needs.
