We also had our results within an hour. The hospital notified the CF clinic there, and they called my pediatrician. She called me and told me of the positive result. After talking to me, she said that the CF clinic representative would be calling me within the hour to schedule appointments and answer questions.
So we spoke to both the pediatrician and the CF nurse practitioner within two hours of the test. I don't know if this turn around would be so quickly done if the result had been negative.
