Hi everyone! Just wanted to let you know the latest on our diagnosis status. My 10 year old son was referred to the CF clinic because of a high borderline sweat test last January- 2 CF clinics, a MRSA culture and another specialist appt. later, his amplified genzyme genetic test came back with no mutations! So I was very pleased with that, but am still very perplexed as the CF dr. still wants to follow him in pulmonary clinic because of asthma and she thinks he has allergies. She ordered allergy testing and some sort of methylsomething challange test. She also referred him for an upper GI and to a GI specialist. But she did say "no CF." We get to the GI dr and she orders an endoscopy with biopsies because of his reflux. She said that it was good that the pulmo dr. was still following him. I just don't know what to think about all of this-he is failure to thrive but his stool elastase came back normal. I am worried about the scope test and wonder what they are looking for. I just feel like this whole diagnosis process is taking a lifetime and I just want to get to the bottom of it. He also will start his growth hormone injections this week because he is growth hormone deficient. He has been tested for celiac it seems like upteem times and it's always negative! Anyone have any idea what they might be looking for with this scope and upper GI? Could there still be a chance he has CF with no gene mutations?
