A TEST FOR CONCENTRATION OF ELECTROLYTES IN SWEAT IN CYSTIC FIBROSIS OF THE PANCREAS UTILIZING PILOCARPINE BY IONTOPHORESIS

¹ Department of Pediatrics, Johns Hopkins Medical School, Johns Hopkins University

A method of performing the test for chloride or sodium in the sweat of patients with cystic fibrosis of the pancreas is presented. It utilizes pilocarpine by iontophoresis and has the advantage of being both rapid and painless. Data are presented to show that the method is reliable.
