title: Diagnosis of cystic fibrosis, by assay of immuno-reactive trypsin in a newborn infant with jejuno-ileal atresias.
abstract: A newborn infant with ante-natally ultrasonically diagnosed small bowel obstruction was found to have two isolated jejunal atresias at laparotomy. Assay of immuno-reactive trypsin enabled an early diagnosis of cystic fibrosis to be made, later confirmed by an elevated sweat sodium.
