I've had all the further testing run under the ANA, and all comes up negative, so my docs are telling me the elevated ANA is "false positive." I understand this can happen, a certain number of people have it elevated, yada yada. BUT, in light of my symptoms,and the fact that it was 1:160 a few months ago and 1:320 last week, I'm concerned.

Certainly, B12 deficiency and autoimmune problems often go hand-in-hand ("pernicious anemia" caused by lack of intrinsic factor, leading to lesser B12 absorption, typically results from autoimmune processes), and the chances of having more than one autoimmune process going on are fairly high. You should have the ANA result further checked with more specific tests for type and pattern (if you haven't already) and I would also get a celiac panel (anti-glidain IgG, anti-gliadin IgA, anti-tranglutaminase IgA, total IgA--deamidated forms if you can) and thyroid function panels (TSH, free T3, free T4, antibodies done (if you haven't already).
