Sixty-six children were evaluated for chloride excretion in sweat obtained by iontophoretic inducing of sweating with pilocarpine. These children were divided into five groups: (1) children with cystic fibrosis, (2) siblings of patients with cystic fibrosis, (3) allergic children, (4) asthmatic children with emphysema, and (5) normal controls. Children with allergy were not found to have chloride values greater than values for normal controls. The values for 2 patients in the total allergic group of 38 did compare with values of siblings of patients with cystic fibrosis.
