Diagnosis of SCID

Before parents know their baby has SCID they may seek help from their family
doctor (GP) or local A&E because of repeated infections, poor weight gain or feeding problems, and the baby may be referred to a local paediatrician. However, the first indication that something is wrong can be a serious infection that causes rapid deterioration in the baby’s condition, requiring urgent admission to hospital, and sometimes to an intensive care unit. As a result of routine investigations, SCID may be suspected, usually because of a low lymphocyte count in the blood. As soon as the possibility of SCID is suspected, the infant will be referred to a specialist immunology centre, and further investigations are then necessary to confirm the diagnosis, and subsequently to determine the type of SCID.
