I see pulmonologist every 6 months now, but saw him every three for a few times at beginning. Note:I'd been to Mayo and was getting stable before I got into Penn. I get a PFT before each visit. I had 2-3 CT's at 12 month intervals, but it's been 18 months since last. PFT's are good and I don't expect another soon. I usually have labs at other MD's and take pertinent ones. I have a couple sputum cups and a standing order for culture, but rarely get anything. My bronchoscopy culture for MAC a couple years ago was negative to the surprise and delight of all of us, so am just dealing with BE. : )
