It can take up to 6 weeks for some mycobacteria to grow, then another week or 2 for the lab to perform sensitivity testing, to see which antibiotics will work best.
My initial diagnosis was pretty fast - at 4 weeks they knew I had MAC, but it took NJH 4 more weeks to come back with the medication recommendation. Some of my later specimens, where I had far fewer bacteria, took as long as 7 weeks to grow to the point where they could test.
