Performance Monitoring in Newborn Screening - a Co-ordinated National Approach
Introduction
In January 2015, the NHS newborn blood spot screening programme was expanded to include four additional disorders. Six conditions are now screened for by MSMS; PKU, MCADD, GA1, MSUD, IVA and HCU. Nationally agreed screening protocols were adopted with specified analytical and clinical cut-offvalues (COV) so harmonisation between labs was important. To assist with performance monitoring and provide assurance of the efficacy of the screening programme, the national co-ordinating centre commissioned a team to collectand analyse population data and results from common IQC material from 14screening labs in England and Wales.
