heh. Thanks Marla. I think I'll be fine not knowing for now. LOL! I've had three neg. tests. Only the CRP is suspect and that could point to anything that is inflamed. My ESR is fine for whatever reason but it's never been terribly high even when I was at my sickest and losing weight at an alarming rate and had my positive ANA titre. Back then my CRP was normal! Go figure.
