Evidence to support continuation or cessation of existing screening programmes should be reviewed regularly. The process for this is currently being revised, which is why this topic does not currently have a review date. The new process will be published in due course. Each programme has an active portfolio of research, evidence and audit to support continual improvement.

More about PKU

Where there is an enzyme block the phenylalanine accumulates in the body tissues and affects the normal development of the brain causing learning difficulties.
