Thank you @johnbishop for linking me here! And thank you for the ANA links. It is always good to keep in mind the fallibility of blood tests - If it were just my ANA I would not be concerned but I have had systemic autoimmune symptoms and the elevated ANA reliably for 2 years now so I am just concerned, understandably.

@becsbuddy Thank you so much for the suggestion and your kind words. I am trying to plan a mayo clinic trip in the summer after I (hopefully) graduate - I'm 3.5 years into my neuropsychology program and am really just trying to make it to the end. I have gone to University of Colorado Anschutz Hospital for 3 years now, and they basically said they couldn't help me anymore once I didn't have MS, and their rheumatology department refused to see me without something more "conclusive" (than an ANA, optic neuritis, and lesions? hm). I have been seeing Dr. Jill Schofield, who is an autoimmune and rare disease specialist in Denver. She is the one who has been able to help me even begin to figure out a lot of this, but obviously it's a pretty big puzzle for any one person to figure out! I will let my family know (they have been encouraging me to consider mayo) that people seem to get good answers, they are just worried about the cost partly.
