I know you all are probably wondering why this is in the adult section. I am 38 and had a sweat test in 1970. I need to have two done to participate in the Aztreanam expanded access program. Insurance may not cover it because I am already being treated for CF. I just want to have an idea of what I might have to spend. Also, besides drinking a lot of water, are there other good ways to assure a "good test". Thanks for your replys.
