Summary of responses to 0.1% cocktail in a CF carrier measured in triplicate at 4 sites with sweat bubble imaging and evaporimetry.

<p>(A) Total volume of sweat imaged after 20 min stimulation at each site (blue columns). (B) Total volume of sweat estimated from evaporimetry measurement of TEWL (see text). The average TEWL baseline for this subject across all 12 tests is shown; this value was subtracted from the transient sweat responses (gray columns).</p>
