I may have mentioned this before, but after clinic appointments, I make a written request to the release of information department and request doctor's notes, lab and culture results, xray reports.... So if you have a specific date when a test was conducted, I imagine you could do the same. It is my understanding thought that the genetic testing that was sent out, can sometimes take 4-6 weeks.
The biggy for us is the culture results. The nurse would call us and say he was fine, only to find out he was growing something that the local clinic didn't necessarily think was a concern, but his primary doctor at the CF clinic in the City DID think was an issue.
