Nevada Newborn Screening Program
Frequently Asked Questions

Nevada State Public Health Laboratory

Why do we need to perform newborn screening?

The purpose of a newborn screening is to identify rare disorders that can cause brain damage or death if not treated early.

Who should participate in newborn screening?

Newborn screening is for all babies. Nevada state law requires hospitals and midwives to collect a screening specimen on every baby born in the state.

When does newborn screening take place?

The first test must be collected between 24-48 hours of age before your baby leaves the hospital or birth center. The second test must be collected between 10-14 days of age.

How will my baby be tested?

A nurse or doctor will place a few drops of blood taken from your baby's heel onto a special test paper for analysis in a newborn screening lab.

How can I get my baby's newborn screening test results?

Ask your baby's doctor for the test results. Another test may be needed for various reasons.

If your baby needs more testing, it is important to act quickly. If needed, treatment should be started as soon as possible.

Why does my baby need a repeat newborn screening test?

Abnormal or unsatisfactory test results will automatically generate a repeat request. It is important to take the baby promptly to a lab or pediatrician's office for the repeat.

What does unsatisfactory test result mean?

Unsatisfactory means the blood sample did not meet lab standards for testing due to any of the following: blood spots not sufficient, clotted or layered, supersaturated, scratched or abraded, wet or discolored, diluted, no blood on the filter paper.

How do I get more information about newborn screening?

Talk with your doctor, midwife or nurse. They will be able to provide additional details about newborn screening.
