Hi - my son was born at 32 weeks. He had ear tubes put in at 1 year and since than has had phnomia 3 times, diagnosed with astham, been on steriods numerous times. This last time he was hospitalized for 4 days and required oxygen. I just had the sweat test done (no one would do one before now even though I asked) and one arm was 36 and other was 40. I am having it re-done tomorrow. Just wanted any thoughts on my issue or suggestions. Thanks! Donna
