I am new to this forum and some what new to CF since my son has been diagnosed 2 years ago. He was sent through all the testing that goes along with it and had a genetic test was done. We were informed he doesn't have the I think "80 common genes" for CF. He has the respiratory problems but not digestive. I assume that because of the unknown gene that is why he is not as bad as others. Should carriers find out what they carry ? Its weird that neither of us (my husband or I) know of anyone in our families that have this. My father & I have asthma, allergies and that sort of thing. It took me a long time to believe it even though the tests tell me different. Since then he has had 2 hospital stays, 1 just last month which woke me up. He has been very healthy and this episode just shows how quick it can turn south. He is better again and life is back to normal for now. What ever normal is ! LOL
