A member asked:

Can someone be diagnose with cystic fibrosis in their 40's?

A doctor has provided 1 answer

As a carrier: Genetic carrier testing: more than 10 million americans are symptomless carriers of the defective CF gene. This blood test can help detect carriers, who could pass CF onto their children. To have cystic fibrosis, a child must inherit one copy of the defective CF gene from each parent.
