Hello! I’m wondering if anyone would be able to guide me in the direction I should go regarding my son and a sweat test that was done back in 2009? My son initially had a sweat test done at an accredited center due to chronic sinusitis and a drop on his growth curve. His pediatrician thought it was unlikely he would have it and said they would call if it was positive. He had his tonsils and adenoids removed shortly after the testing..he was already scheduled to have them removed. Fast forward to a couple of weeks ago when I was seeing a specialist for myself. He entered me and my kiddos into the online chart system. When I came I home I looked through all of my kids lab tests out of curiosity and found my sons sweat test. I was shocked to see it was positive at 65 and that they said it needed to be rechecked. I had no clue about this. Should I take him in and ask ped to recheck it? He is overall healthy..2 cases of pneumonia in almost 14 years and the sinus issues are pretty much improved. He has been followed the last year for some slow growth...mainly height though. My other children have all had sweat tests done for various reasons as well. No positive tests with them. Thanks for your input.
