What chances 33 y/o male has cystic fibrosisis? i do have a child & i never had breathing issues or pancreatic insufficiency, issues. only sinusitis.

Not great: The fact that you are 33 and have only had sinusitis--which many non-CF people experience--and no other lung or pancreatic signs or symptoms suggestive of CF would make CF very unlikely. You can always arrange for a sweat test

CF DX: There are only about 18 cases of "Late diagnosis CF" in Canada each year : http://www.cysticfibrosis.ca/about-cf/living-with-cystic-fibrosis/adults/late-diagnosis/ If concerned Drs. do a sweat test. Genetic testing will also answer your concerns and tell you about carrier status too. See www.cff.org/What-is-CF/Testing/Carrier-Testing-for-CF/ Is there CF in your family?
