We have asked a CF Clinician to answer you enquiry.
This is below:
True carriers do not suffer symptoms. If there are symptoms suggestive of CF it is worth investigating . We have sometimes found that people who were previously labelled carriers on standard testing from a few years ago may turn out to have unusual gene changes that can now be picked up on the latest testing. In other words it turns out they have a second gene change and actually have CF.
So on the basis of this I would go to your GP and ask for further testing to rule out you having full blown cystic fibrosis. If you have any further queries, please contact our helplnie on 0300 373 1000
