Mom2Bri...hello there! This is a funny coincidence but my daughter just did a sweat test at Valley Children's Hospital in Madera recently too! We live in Visalia, California. First of all, best wishes getting a diagnosis. We've been working on one for three years now for our 7 year old daughter, so I know the rollercoaster you are riding. She's had odd, foamy, loose and floating stool for 5 years now, and 3 years ago she had some GI bleeding episodes, she's gone through 3 colonoscopies, had several significant findings on biopsies during these procedures but none of them led to a diagnosis. Her sweat tests were in the mid 30's the first time, and then dropped way down to 20. I ask myself, is it possible for a sweat test to vary by that much??? She's had one positive fecal fat test indicating fat malabsorption, and then one just came back last week negative. We are waiting on a pancreatic elastase test. I am planning on asking for genetic testing. Almost every stool of hers floats. Anyway, I think it's interesting we live in the same area. By the way, I heard from one source that Madera is an accredited CF center, and another that they are "working" on it.
