@mtinderscott2626 I would say NJH is the best and have heard from others that it has the best lab. I don't know Mayo's protocol but at NJH, I was there for 8 days of testing and appointments. I had a hospital room but was an outpatient, so I didn't stay overnight but in a nearby rental home. I was diagnosed with MABC which is more difficult to treat than MAC, so maybe you would stay less days. That said, you want to know the extent of your infection which is measured by: 1. the bacterial "count", 2. your CT scans, and 3. how you feel. People live with MAC for decades without treatment. Are you nebulizing? Did your CT show cavities? If nodules, the best thing for you to start with is nebulizing 2/day with 7% saline. Cavities are more difficult to treat. There have been limited studies that have shown 25% of those infected with nodular MAC have been able to avoid the "big 3" with nebulizing (7%, 2x/day). Portland is just wrapping up a study with a larger test population and hoping results will be published in the next few months. I was diagnosed with M. Abscessus, macrolide resistant, which is much more difficult to treat. Nebulizing has really helped me. I hope this message has helped. Good luck and keep us posted.
