The objective of this study was to determine the prevalence of CF among a group of high-risk children with suggestive clinical features in the main referral hospital in Iran.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>MATERIALS AND METHODS:<\/jats:title>\n                    <jats:p>This study children consisted of 505 patients who had presented with one or more of the following symptoms: chronic or recurrent respiratory symptoms, gastrointestinal symptoms as rectal prolapse, steatorrhea, hepatobiliary disease as prolonged jaundice, failure to thrive, hyperglycemia and glycosuria, hypochloremic metabolic alkalosis, hypoprothrombinemia, anemia or edema, and positive family history of CF. Patients were screened using pilocarpine iontophoresis to collect sweat and chemical analysis of its chloride content with classic Gibson and Cooke technique.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS:<\/jats:title>\n                    <jats:p>Of 505 patients, 89 (17.6%) had positive sweat chloride screening test.
