An ANA blood test can confirm or deny an autoimmune disorder.

Yes I have hashimoto's thyroiditis which is an autoimmune disorder

Yes I've been told that I do.

I haven’t per se, but I’ve had autoimmune markers tested positive over the last two years. I’ve been tested for everything under the sun, including MRI, CT’s and countless labwork. Everything comes out negative. I always wonder if I do have a autoimmune disease but it’s not being caught yet. My recommendation is to find a good rheumatologist who listens to you and will test you for what you want. Best wishes!
