Overview
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.
