PKU is a blood test that is completed on newborns by doing a heel poke when they are around 48 hours old. This screening tests for over 30 metabolic and endocrine disorders including phenylketonuria (PKU), cystic fibrosis, congenital hypothyroidism, as well as many others.

Infants affected with these disorders are known to have better outcomes if the disorders are detected early. Following the blood test, you will be notified at home if anything abnormal is found.
