Does a positive result mean I have cystic fibrosis?

No. A carrier result means you carry one variant copy, which is not the same as having the disease. Most carriers are healthy. A genetic counselor can explain the result.

If my result is negative, can I still be a carrier?

Yes, though the chance is smaller. No screen checks every known CF variant.

Should my partner also be tested?

Reproductive risk depends on both partners' carrier status. A clinician or genetic counselor can advise on partner testing.
