There’s no single test to diagnose autoimmune disease. Doctors review symptoms combined with specific blood markers and in some cases, a tissue biopsy. Diagnosis can be difficult because these symptoms can come from other common conditions. Many people report that it can be a long journey before getting a confirmed diagnosis.

Has this been your experience, @hmccarth5?

@hmccarth5 i, too, have been noticing the rise in autoimmune diseases. The following article says a little about the issue, but not really enough. It is nice to know that research is looking into this.

Have you tried checking ‘rise in autoimmune diseases’ on Google Scholar?

Yes I would think so and many are very unique without so called classic signs
