What does PKU test for in newborns?
A PKU screening test is a blood test given to newborns 24–72 hours after birth.

Phe is part of proteins that are found in many foods and in an artificial sweetener called aspartame.
What test is used to identify babies with PKU soon after birth?
The screening test is also called the ‘heel prick’, ‘Guthrie’ or ‘PKU’ test. The screening test is done when your baby is 48 hours (2 days) old or as soon as possible after this – it can be done in hospital or at home. Your midwife will collect a small amount of blood from your baby’s heel onto a blood spot card.
