Cystic fibrosis sweat test -- who gives it?

DNA vs. sweat tests. For sweat tests, do not trust a laboratory which is not accredited by the Cystic Fibrosis Foundation. "Sweat tests should be done at a Cystic Fibrosis Foundation-accredited care center". See http://www.cff.org/AboutCF/Testing/
CF centers. Usually the pediatric side of the CF center does the sweat chloride test... It isn't done as often anymore as most cases are picked up @ biirth with standard genetic screening. Your pulmonologist will know.
Not necessary. CF screening is a dna blood test now, given to all newborns. Any hospital that delivers babies can do it. The sweat test is not done as often any more, but if you want it you should see a pulmonologist, they will probably do it in their office.
