I understand, Harriet! Jordan had 3 positive sweat tests - all over 100. My older son, Bronson was sweat tested then too. His results were (and I quote the pulmo) "high-borderline". I was told he was a carrier. LATER, after finding this site, and learning so much, I wish I had pushed for further testing on him. He also has a LOT of symptoms! My youngest son was not tested at the time, because he has a diff. father.
This site has taught me that CF is NOT a simple disease. There are so many shades of gray! I know there is still much to be learned.
