That is my literal, exact same result for ANA. 1:320 homogenous pattern. I have RA - seropositive with anti-ccp antibodies and a high rheumatoid factor. Negative for sjogrens. Negative for every other autoimmune disease under the sun, including lupus. RA is controlled by meds and isn't much of an issue anymore. Small fiber neuropathy, full body, rages on and on (even with normal inflammation markers) in what I assume is an autoimmune process without a name. It's truly a big mystery but as far as I have been told, a positive ANA indicates, well, any autoimmune mechanism.
