newborn screening programme

Congenital adrenal hyperplasia

Congenital Adrenal Hyperplasia (CAH) is the name given to a group of disorders. These cause impaired production of a chemical called cortisol.

UK NSC screening recommendation Based on the last UK NSC review of this condition that occurred in November 2021.

Screening is not currently recommended for this condition.

Newborn bloodspot screening for congenital adrenal hyperplasia is not recommended because:

  • aspects of the condition remain unclear, for example at what point children with CAH develop symptoms in their first month of life
  • current evidence suggests that some children would present with symptoms before the results of their screening tests would be available in the UK, and therefore they may not benefit from screening
  • current tests are not accurate enough and may miss babies (false negatives) or tell parents their baby has CAH when they do not (false positive), although some tests used in combination with an initial test show promise for reducing the number of false positives
  • further studies (ideally conducted in the UK) could help to improve the evidence relating to how good the tests are
