Re: confused about test results.....
In order to have CF you have to have two copies of the CF (mutated gene) for example, my son has two copies of Delta F508. If you have only one copy then you are a carrier like my husband and me. There are cases where people have not been diagnosed until adults. Are you going to see a pulmonologist and what further tests are they going to do? I would begin writing down any questions you might have for the dr so that when the time comes you won't forget. Best wishes!
