Metabolic Diseases, Phenylketonuria
Conditions
Brief summary
The aim is to demonstrate a new application for a blood collection device. This device is already widely used in pharmacology. It is not currently used for metabolic diseases. Its ease of use enables repeated sampling at home. What's more, the device can be sent by post, making it ideally suited to the needs of this cohort of children, whose phenylalanine levels need to be monitored very regularly.
Interventions
Comparison of phenylalanine concentrations in the new device with those in the current device (blotter).

Eligibility
Inclusion criteria
* Children aged 3 months to 18 years * suffering from phenylketonuria or hyperphenylalaninemia * who have had a capillary and blood test including a phenylalanine assay at CHUGA * Whose parents or legal guardians are affiliated to the social security system. * For whom parents or legal guardians have not objected to the MitrAlanine study.
Exclusion criteria
* Parents or legal guardians opposed to the MitrAlanine study
