Wales funds new lab to add tenth newborn screening test

A £1.21 million laboratory at University Hospital of Wales will allow newborn screening to expand beyond the nine conditions currently tested for, the Welsh Government has announced. An additional £529,000 has been agreed to introduce testing for hereditary tyrosinemia type 1. The existing facilities lack room for more tests. The announcement gives no opening date for the new biochemistry lab or start date for the additional test.

What changes, and what remains under evaluation

The service screens around 28,000 babies a year. The new lab will also provide capacity for future research and recommended tests. Spinal muscular atrophy and severe combined immune deficiency remain under evaluation. The investment puts Wales in a position to explore participation in that work and any future national screening; it does not introduce those two tests now.

Screening is followed by further tests

Public Health Wales says the bloodspot sample is usually taken five days after birth, using blood from the baby’s heel. Most babies screened do not have one of the conditions. A suspected result needs further tests to confirm a diagnosis. For babies who do have a condition, screening allows earlier specialist care and treatment. Parents with questions can speak to their midwife, as the official information leaflet advises.
