[The sweat test. The proposal to revise the concept of the "grey zone"].
The results of the sweat tests performed in Turin CF Centre in the last four years were reviewed. The opportunity of changing the range of doubt, commonly situated between 40 and 70 mEq/l Cl-, has been considered. The sweat test appears worth to be repeated only for values > 60, unless clinical signs and symptoms persist.
