I did get a blood test and x-rays done by my family doctor because my specialist wouldn't do it. I didn't have elevated levels, nor did it show in my x-ray, but while I was in hospital the infectious disease doctors speculated on whether that was my problem or not, because I do in fact culture it all the time. My doc justs keeps telling me that its BS, that he as a rule does not treat aspergillus, that while I do culture it and have problems breathing, and do present most of the symptoms, he believes that aspergillus wouldn't be the cause of my problems for whatever reason. I mean really, if it is a problem for me, why wouldn't they treat it? Why leave it untreated if it really is causing problems? I don't get him saying that he doesn't treat it as a rule...
Edited to add: steroids do help bring your levels down. My family doctor told me that since I'm on symbicort which is a steroid, that it should help with my levels. Short of taking prednisone ( which does cause high blood sugars) or an antifungal med, there's nothing you can do to get rid of it. Like I've said, many CFers culture it without even knowing it and don't have a problem with it. You only have to worry about it if you're allergic to it.
