@jasmine321 Hi Jasmine, welcome to our Connect group. Well, that is certainly disheartening news after having been on those antibiotics for a year. I believe you when you say you have mac again, but I am curious how your dr. got such a fast diagnosis? It takes 6-8 weeks to culture a sputem sample and you mentioned that you had the sputem test done last week. Have you had a chance to read over some of our older posts or read our topics in the Discussion Board? It is located on the 'Mac and Bronchiectasis' home page. There is a wealth of info in our threads (conversations). My next reply to you will be about lavages.
