@toni1132 I think the nose and sinus possibly could show MAC when our lungs have MAC, what comes from my nose is the same colour that comes from my lungs. Not sure that they have tested this yet. Take care Heather

@woot Hi there! Your sputum sample containing saliva might show MAC, but the lab and doctors want to keep things separate. My ENT at Stanford regularly cultures samples from my sinuses, and I do have colonized m. Abscessus in my sinuses (along with a host of other pathogenic and normal critters.) I’ve never sent a sample from my sinuses in to the lab.

I have MAC in my lungs, too, but hand deliver my own self-induced samples to the lab.
