| pubmed-article:869497 | pubmed:abstractText | The measurement of sweat chloride concentration was investigated by using the Orion 417 skin chloride electrode. The effects of variation in pilocarpine concentration, iontophoresis period, and sweat collection period were also investigated. The results show that the sweat chloride concentration is directly related to the amount of sweat produced. When the amount of sweat collected falls below a certain level, there is an apparent increase in sweat chloride concentration. A procedure is recommended for the measurement of sweat chloride concentration which offers good precision (coefficient of variation 9.8%) and the minimum of inconvenience to the patient. | lld:pubmed |
