Yes it's quite possible. Six years old is not too old to be diagnosed. As far as the parental screen, if you don't carry one of the more common genes, it could've gone unseen, yes. And for the newborn screening, there are very often false negatives on CF tests. We see people coming through here saying that they got 4 negative sweat tests before they finally got the correct positive one.
It also depends what the prenatal tests and newborn screening tested for. Many states don't do newborn screening for CF. Many insurance companies won't cover prenatal carrier testing on the mom unless there is a reason (family history of CF). To test for CF (or to see if a parent is a carrier)- it has to be a specific type of test - those general prenatal/newborn tests are not for CF. The most accurate way to test a six year for CF is the sweat test. It is very simple to have done.
Yes it is possible. My son, was 2 when he was diagnosed. It was completely missed because his newborn screen was negative for CF. What you don't realize is in most newborn tests, they only test for the 1 major mutation and our son had 2 really rare mutations. Ones the CF doctors had to research to get information on. They still don't know much about them or how well he is expected to do. It is all overwhelming but we are better for knowing because now he gets over a cold in 7-10 days as opposed to 3 weeks. Hope this helps.
<img src="i/expressions/heart.gif" border="0">Hello, It is very possible my son was 3 months old when it was suspected that he could have CF,however my girl age 6 who in hind sight had ALL the symptoms of CF and who tested negative via a sweat test in her early years
was diagnosed via genotyping at the age of six and my son also that was five yrs ago

To the last poster, I have a few questions regarding the diagnosis of your older dd if you don't mind. My ds had a negative sweat test and a negative genetic test from genzyme but his drs still suspect he has cf. When your dd tested neg on the sweat test, was it at a hospital that's acreditted by the cff?? Also, do you by chance know what her sweat chloride number was and what two mutations she has? Were her mutations rare? THanks!!!
