Brand new here. Just curious, will patients with AS have a positive ANA?

Not always, but sometimes. ANA is more closely associated with lupus and Crohns, which AS sufferers will sometimes develop.

I've developed ANA antibodies while on Humira, and my rheumatologist thinks it is the result of being on Humira. She said it's nothing to worry about for now.

ANA can go up and down, positive sometimes and negative at others. It's not very specific, but when symptoms and a positive result come together, it could point the way for a rheumy. Usually mine is negative, but during a flare, it was positive to 1:80, which isn't really positive enough to mean anything at my lab. A good source of info for lab questions (besides asking a medical laboratory scientist or your doc) is www.labtestsonline.org, which is sponsored by a number of lab-oriented companies and accrediting agencies. Lots of good information to be found there.
