[Diagnosis of mucoviscidosis by examination of sweat: value of conductometry].
Two methods for the determination of sodium in the sweat after stimulation by pilocarpine-iontophoresis were compared in 227 patients, among them 27 with a known cystic fibrosis. These two methods were 1. the standardized method by flame fotometry (State Pharmacopoeia of the German Democratic Republic) and 2. the determination of the sweat conductance by the new apparatus "CF-Conductognost". Both methods showed a good correlation. We recommend the conductometry for the decentralized screening because it saves time and gives results immediately. But in all patients with a questionable or pathologic value of conductance the sweat test should be repeated with the standardized method. This concerns only about 10 per cent of all patients.
