What is Heel Prick Screening?
Heel prick screening is a national newborn screening programme offered to all babies, usually performed around 3-5 days after birth, testing a small blood sample for a range of rare but serious conditions that can be treated more effectively if caught early, before symptoms develop. Conditions screened for include PKU, congenital hypothyroidism, cystic fibrosis, and several other rare metabolic and immune conditions.
For most of these conditions, early treatment — often before any symptoms would otherwise appear — can prevent serious, sometimes irreversible complications, making this simple test one of the most valuable things done for a baby's long-term health.
