An evaluation of the symptoms and progression of a disease.
It is always a good idea to try and find an accredited Cystic Fibrosis Care Center in your area. CF Foundation has a locator for all United States here: http://www.cff.org/aboutCFFoundation/Locations/FindACareCenter/
When you go in for your CF Clinic appointments, they will do a full clinical assessment. Usually they check weight, height, O2 saturation, blood pressure, lung function, GI tests if needed. They also listen to your lungs to see if you are moving air well or if you have "crackles" or "wheezes". Sometimes they will also do a walk test with the physical therapist to see how you are tolerating activity.
