I can't seem to find the answers I am looking for. I have a 14 month old going for a sweat test in two weeks. The doc's say it's just to rule it out, but I am worried mom. He is under weight and was sent to the GI in June - he tested for Celliac and Crone's but both were negative. He has several of the symptoms, but no breathing or lung issues so far. Has anyone experienced any thing like this. I just want to prepare myself better then the doc just saying it's to rule it out. I did have cousin with CF. I know it's somewhere in my family. I don't know if my husband and I have ever been tested. I see the OB on Friday (I am prego w/ 4th) and will ask him to dig through my paper work. Anyone with any answers?
