Re: Sweat test result question...
I have a son w/ cf whose 3.5 yrs old-- I completely agree that you will need to find an accredited CF center. Ask your doctor when you see him on Monday, they are really the key players you will need to talk to about this, no matter how far away they might be. Are you able to find the website??
I would recommend a genetic blood test as well.
The one thing to remember , if this does turn out to be CF is that your son is the same person- the day before, or the day after a positive result. The issues and struggles you've had don't change, but there is a REASON for them now. A diagnosis can get you on the right path so you can manage your son's care as opposed to doing it piece by piece- no weight gain, cough, reflux, etc.
I wish you lots of luck- these boards are a great resource.
