Newborn Screening (PKU) Test
What is Newborn Screening and why does my baby need it?
A newborn screening (PKU) test is usually performed when your baby is one to two days old, as required by law in the United States. It screens your baby for certain serious medical conditions, such as cystic fibrosis and sickle cell anemia, among others, that may go undetected without this testing. Early detection and treatment of these conditions can help prevent death, mental retardation or physical disability.
If the test needs to be performed again, does that mean my baby has a medical condition?
There are many reasons why the laboratory may decide to re-test your baby. The most common reason is if the first sample did not contain enough blood to complete the required tests. The does NOT necessarily mean that there is anything wrong with your baby. It simply means that another sample of your baby's blood is required to complete the necessary tests.
If the results of the first tests are questionable or suggest a possible problem, another sample will be requested and the test will be repeated. If the results are abnormal for a second time, your doctor will talk with you about the need for further medical testing.
When will I know the results of my baby's tests?
If the results of any baby's tests are abnormal, your doctor should notify you immediately and provide you with further instructions on next steps. If the baby's test results are normal, they will be mailed to your doctor approximately two weeks after the screening was performed.
