All Newborns |
Recommendation |
Grade: A
|
Screening Tests |
Screening for PKU is mandated in all 50 states. Methods of screening vary.
Three main methods are used to screen for PKU in the United States:
- Guthrie Bacterial Inhibition Assay (BIA)
- Automated fluorometric assay
- Tandem mass spectrometry
|
Timing of Screening |
Infants who are tested within the first 24 hours after birth should receive a repeat screening test by 2 weeks of age.
Optimal timing of screening for premature infants and infants with illnesses
is at or near 7 days of age, but in all cases before discharge from the newborn nursery.
|
Treatment |
It is essential that phenylalanine restrictions be instituted shortly after birth
to prevent the neurodevelopmental effects of PKU.
