we know that we have 4 levels of pku.
Hyperphenylalaninemia, with Phe levels that are slightly above normal range: 120-600 µmol/L (2-10 mg/dL)
Mild, with the lowest blood Phe levels: 600-900 µmol/L (10-15 mg/dL)
Moderate or variant, with blood Phe levels somewhere in the middle: 900-1200 µmol/L (15-20 mg/dL)
Severe or “classic” PKU, with extremely high blood Phe levels: >1200 µmol/L (20 mg/dL)
but these numbers are related to w2hich period?
somebody says that these levels of pku related to the number of phe at newborn screening and somebody else believes that these levels considered when pku peole left their diet for a period of time. what do you think?
