We promote high standards of practice and encourage collaboration in newborn biochemical screening across the UK   


The UK Newborn Screening Laboratory Network (UKNSLN ) is an association of NHS laboratories which provide screening services to newborn babies for a number of inherited and congenital diseases where early treatment can prevent or limit damage to the baby.

The laboratories screen all babies for the following conditions which have been approved by the National Screening Committee:

congenital hypothyroidism (CHT), phenylketonuria (PKU), medium-chain acyl-CoA dehydrogenase deficiency (MCADD), maple syrup urine disease (MSUD), homocystinuria (HCU), glutaric aciduria type 1 (GA1), isovaleric acidaemia (IVA), cystic fibrosis (CF), sickle cell disorders (SCD) and other significant disorders
