Autoimmune Screening Panel in Arizona

What this test measures

Autoimmune conditions develop when the immune system mistakenly targets healthy tissue. Because different conditions target different tissues, no single test covers everything. A panel approach checks several markers at once, which helps clinicians decide whether more focused testing is warranted based on the pattern of results.

The panel typically includes antinuclear antibodies, rheumatoid factor, anti-CCP, inflammatory markers such as ESR and CRP, and sometimes complement proteins. Each marker reflects a different part of the immune response. Some markers are sensitive but not specific, meaning they can be abnormal in people who do not have an autoimmune disease.

Results are reviewed as a group rather than in isolation. A positive marker does not by itself confirm a diagnosis, and a negative panel does not rule one out. Clinicians combine the findings with symptoms, physical examination, and sometimes imaging or referral to a specialist.
