I was diagnosed as a infant under 6mts.? failure to thrive and constant breathing problems. This was 1954 and the sweat test back then was ???? anyway it came back borerline, we went to clinic every month, got meds and left the one thing I remember is my doctor's name Dr. Allen and that every time I went there was always another child missing? I had a favorite his name was Calvin and one year he was missing as well. He was a young black child, this was always stated as a white disease??? When I was 8 they repeated the sweat test and was told not to come back as the test was borerline again. But I lived the life of a sick child and young adult. We were quite poor and my Mom just did not know any better.she believed them so I went untreated for years. It wasn't until my mid 20's after removal of my gall bladder that the surgeon suggested a CF clinic after I told him some of my history. I started at a CF clinic at that point and took it upon myself to get the proper care, still borderline sweat test and only lung issues at that point. I think I was in my early 30's that my doctor finally ordered a full panel blood work where they found my second mutation, but I also made a trip to UNC at Chapel Hill and they did what was called a nasal choloride test, which came back positive for CF. Many years have passed, much progress has been made. I now have the digestive issues as well, and a lot in between but I also turned 60 in December. I am sure this is so hard on parents today. We know early intervention is the best, finding answers and getting your baby the proper care. I really hv no idea how I am here today typing on this site, considering so much neglect in my healthcare. Please give yourself credit for doing all you can to this point. Don't be so hard on yourself, and also trust yr. instincts as well, we put our faith in the medical field as they are more educated than we are, but if it does not feel right. question all that is being done. I will pray for you. Sorry this sounded like a short story of me, that was not my intention. Every case of CF is different. Pat
