@kananab thank you for replying. I am currently being assessed at UCLA for a MAC infection of the lungs. They are also going to start treating me for my CVID. They think I may have more things going on in my lungs besides the MAC. I also have Bronchiectasis. They want to change me from IVIG to SCIG. We are having problems with that because there is a blood shortage. I am waiting for tests. I am having a hard time producing a sputum sample. Finally somewhere to find out more about CVID.
