Patient's question:
Does jaundice affect the PHE value? How should this jaundice be treated for the best effect?Doctor's answer:
PHE is the preliminary screening result for phenylketonuria. Normal newborn values are generally less than 2. It is an amino acid metabolic disease. The main symptoms are severe mental retardation and abnormal hair and skin. Newborn PHE screening may have many false positives, most of which are related to drugs. Neonatal jaundice does not show an effect on PHE. When a newborn's PHE value is high, it is usually necessary to combine conditions such as EEG for a clear diagnosis. Parents can first not worry and observe the child's intelligence, skin, and hair, or undergo regular reexaminations.
