Newborn screening is a preventive measure in the field of population medicine. It is used for the early detection and quality-assured treatment of all newborns with certain treatable endocrine, metabolic and immunological diseases. Genetic diagnostics can help to confirm the diagnosis from the screening examination. Since the affected enzyme/protein is already known from the screening result, the relevant genes are specifically investigated.
