@hayn3705 I was dx with mild bronchietasis in 2016 and MAC/MAI. I have no symptoms from the NTM infection so my Dr and I agreed NOT to treat with the antibiotics. I was told to use an Aerobika for lung clearance. Since that time I moved and switched pulmonary Drs. He was also in agreement about no antibiotics yet. After reading about nebulizing with saline on this forum and in other studies, I requested the prescription from my Dr so he prescribed .9%. I now use 7% saline, and still have no symptoms from the NTM. I still do my lung clearance 2x per day. I haven't had a sputum test in 2 years, (which I will probably make an appt for this summer), and my CT scans remain the same. Maybe you can request it from your Dr. It can't hurt but definitely may help. And definitely ask about lung clearance. That's very important with bronchiectasis to keep the lungs clear of mucus.
