Degrees of CF?
Hi Amy, welcome to the site! <img src="i/expressions/face-icon-small-smile.gif" border="0">
There are different severities of CF. My CF is "mild" right now (my PFTs are currently 117%), but CF is progressive in nature, so I'm not sure how long I will be a "mild case."
It's good that you are going to take him back for another sweat test. My first 3 sweat tests were positive, then they tested me at a CF center, and the sweat tests kept coming back inconclusive (couldn't say yes or no), so they decided I didn't have CF when I was an infant(this was before they discovered the CF gene, etc)
Anyway, I did not have typical CF symptoms as an infant other than losing weight and having salty skin. My lungs are great, my main problems are sinus issues and some digestive problems. After having 2 sinus surgeries & other random problems and researching CF on the internet (as it sounds like you did), I also read about mild cases, so I decided to get tested again 2 years ago. Sure enough, the sweat test and the genetic test came back positive.
I know this must be stressful on you taking him back to get another test, but I hope it goes well, and that you hear good news that he does not have CF. good luck!
