Overview
- The Department of Health and Social Care said planning is under way for a large-scale NHS evaluation that will begin in October 2026 and screen hundreds of thousands of babies in seven specialised newborn screening laboratories covering roughly 72% of births.
- Campaigners led by Jesy Nelson, whose petition gathered more than 150,000 signatures, have publicly demanded a clear timetable for full national coverage and called the limited rollout a 'postcode lottery' that will deny some babies timely diagnosis.
- Officials say the decision to start with seven sites reflects gaps in the current evidence base and the need for specialised equipment, and they deny that excluded babies are being used as a control group in the evaluation.
- Clinicians and families stress that pre-symptomatic identification matters because treatments work best when given early, and campaigners pointed to cases where early therapy led to dramatically better outcomes for children with the same diagnosis.
- Ministers say they are considering ways to extend the programme if evaluation results support it, so the coming months of data collection and lab upgrades will determine whether and how quickly screening is rolled out to the remaining regions.
