Abstract
Cystic fibrosis, the most common congenital lethal disease of western Caucasian population is usually diagnosed by the finding of Na+ or Cl- levels of more than 60mEq/L in sweat. Pilocarpine iontophoresis was done to collect sweat; conductivity of sweat is extrapolated in the standard graph to find out concentration and this was compared with the standard method i.e. flame photometry. 19 patients of chronic chest disease were studied and one patient was detected to be havihg cystic fibrosis.
