Valerie,
I also think symptoms are more important that genetic diagnosis. Mostly because until CF was finally confirmed last year, that was my story. I was "normal" until I was 21. So in other words, had I been been born in a time when there were genetic tests, I would have had the mildest case ever until I was 21 when all hell broke loose. My doctor said he strongly suspected a mutation of CF, which I promptly denied. I was 21 and I didn't "like" that diagnosis. LOL.
I has all the lung manifestations that are usually associated with CF: Pseudomonas, staph, MAC, hemoptysis, drug resistance, bronchiectasis, constant infections, chronic cough.. the works. High normal sweat test (I don't know how high). I had the genetic test when it first came out and they identified 1 gene (only about 80 had been discovered.) I still didn't think I had CF, although I kinda DID at the same time. I had a different doctor at this time who said probably CF and his partner ran an adult CF group through a major medical center and was annoyed at me when I said that I didn't want to join.
When the full panel test came out, I still didn't want to know. My insurance was willing to pay for anything the doctor ordered. Nothing would have changed in my treatment, so I liked deluding myself.
Lat year, when I signed up for a special insurance program in CA, to give myself peace of mind (since my insurance premiums had tripled in one year), they made me get the test. And now I wanted it to be positive very badly. I finally realized no matter what you call it, I had the same symptoms. I was thrilled when the results were positive, which I know sounds bizarre -- because I couldn't sleep any more worrying about my insurance.
So after a lifetime of being sick, I now understood what was wrong with me. And the other good thing about knowing is that it may be helpful to know for future treatments which require known genetic mutations.
In my book, this is not a contest. Whether someone is mild or severe, it's still a big ol' pain. It's not being fun being sick, it's time consuming, and affects every one you know in some capacity.
So I guess there are different routes for getting into the club, but in the end we're still all members.
One more thing, I noticed that your insurance won't buy you a vest. The last time I was sick, and had bleeding, I couldn't use my "Flutter" which is a mucus clearing device (in case you didn't know) my doctor suggesting trying one of those giant massagers or a kind of a massaging jacket that you wrap around yourself. I have used both.
I really like a giant massager that I bought at Brookstone. It has different speeds and if it is too much, you can use it over a towel -- if your doctor thinks it's right for your son. I used postural drainage with the massager. After the bleeding stopped, I added a .09% saline and then worked my way back up to a 7% H.S. and it all worked very well for me.
These days, I use H.S. and the Flutter.
