Thank you so much, V!  Something interesting has happened since I wrote that: I had to get a fresh supply of nebulizer solution and when I went to throw out the old box (from Nov 2011), I discovered that it EXPIRED TWO MONTHS AGO!  Now I am feeling even better from non-expired solution (just today) and wondering if that could have also thrown off the tests - depending on what actually it degrades into! But the good news is, I am feeling better and better - so how bad can it be?    I also got a very nice call from a nurse connected with my insurance, to follow up how I am doing and if I am in need of anything.  I gave her quite an earful of stories, I was just wound up and she happened to call just then!     I am also starting to get out now - it does tire me somewhat, but then I can take a good NAP, because being with people is GOOD.  I sat in the hospital bed long enough (but the nurses were really good too, and everyone explained things and gave me choices - it really felt like a team effort.  Wow.... Thanks for writing, I always love to hear form you! How is your healing going? Ellen
