Newborn Screening—Congenital Disorders
A newborn baby can look healthy but have a serious disorder that cannot be seen. If not treated, these disorders can lead to slow growth, blindness, brain damage, or possibly death. Early treatment can help prevent these serious problems. This is why in Wisconsin babies are tested right after birth for rare disorders.
What is Newborn Screening?
Wisconsin law requires that all babies have the newborn screening done before they leave the hospital. Babies born at home must be tested within a week of birth.
The screening is done by pricking the baby's heel and collecting a small sample of blood. The Wisconsin Department of Health and Family Services oversees the program and all blood samples are sent to the State Laboratory of Hygiene in Madison for testing. Learn more about Newborn Blood Screening.

Will my doctor repeat this screening at my baby's first visit?
Your baby's healthcare provider will receive a report of the test results.
Be sure to ask for the results from your baby's healthcare provider.
Sometimes the test done at birth needs to be repeated to be sure of the final result. This is very common because babies are screened when they are only 24 hours old and sometimes the newborn screening program needs to have a second look at your baby's blood before they can report a final result.
