What can trigger an autoimmune disease?
The exact cause of autoimmune disorders is unknown. One theory is that some microorganisms (such as bacteria or viruses) or drugs may trigger changes that confuse the immune system. This may happen more often in people who have genes that make them more prone to autoimmune disorders.

What does an autoimmune flare feel like?
Flares or “flare-ups” are a classic sign of an autoimmune condition. Flares are the sudden and severe onset of symptoms which can include redness, heat, pain, or swelling. Flares can be triggered by different factors, such as stress or sunlight.
Do autoimmune diseases show up in blood tests?
One blood test for autoimmune disease is C-reactive protein (CRP). Another test is ESR (erythrocyte sedimentation rate) – this is done to assess an inflammation that is not from an infection or due to other reasons. One of the most common blood tests for detecting autoimmune disorders is ANA (antinuclear antibodies).
