Hi I'm new here and looking for some advice. My son has just had his second elevated sweat chloride test done. First one done at non CF center, second one done at UC Davis, accredited CF center. His symptoms are nasal, nose polyp (1), allergies, slight loss of taste / smell and slight digestive issues. We are hispanic and I was told yesterday that he must have some mild form of it and rare mutations and it was recommended that we go to UCSF instead because they are the best here in the Bay Area (Northern California). This is a relatively healthy kid no hospitalizations and cleared by pulmonologist recently of any pulmonary disease or asthma, in fact he said that he would have never ordered the sweat chloride test on my son (the allergiest did), he told me "look at your son that's a healthy kid can't be he's 5' 8" 201lbs and heavy set, he can't go almost 17 years with no diagnosis of CF, can't be". Obviously he was wrong and I'm devastated but trying to be strong, I know he needs me to be strong so he can fight and be strong too. If this were your child what center would you use UC Davis or UCSF, UCSF supposedly does alot of the current research. His OTO ordered the first round of testing for 32 common mutation and checking for hypothyroidism and diabetes as it's very prevalent on both sides of our family but thinks it will come back unfound guesses it's a rare mutation. I know I need to push for Full Ambry analysis which I will as soon as we have our first work up at UCSF. Any advice out there or suggestions on which center to use. Thanks for your support and help.
