  • Blood spot phenylalanine and tyrosine levels to measure metabolic control
  • Changes to dietary management and any adaptations arising from incorporating PKU Sphere
  • Compliance/adherence of patients to their recommended amount of protein substitute prescription.
  • Tolerance of PKU sphere with respect to gastrointestinal (GI) symptoms and pregnancy associated nausea and vomiting.
  • Acceptability of concurrent protein substitute(s) (if applicable).
  • Nutritional status and weight management.
  • Routine standard of care data on the final pregnancy outcome and postpartum.
