Autoimmune Disorder Panel in Illinois

An autoimmune disorder panel is a group of blood tests used to look for signs that the immune system may be attacking the body's own tissues. It is often ordered when a person has unexplained inflammation, joint pain, fatigue, rashes, or other symptoms that could suggest an autoimmune condition.

What it measures

Antinuclear antibodies (ANA) — A common screening marker; a positive result can occur in several autoimmune conditions but also in some healthy people.
Rheumatoid factor (RF) — An antibody often found in rheumatoid arthritis and sometimes in other inflammatory conditions.
Anti-cyclic citrullinated peptide (anti-CCP) — A more specific marker for rheumatoid arthritis.
Erythrocyte sedimentation rate (ESR) — A general sign of inflammation in the body; it does not point to one specific disease.
C-reactive protein (CRP) — Another general inflammation marker that can rise with infection, injury, or autoimmune activity.
Complement proteins (C3, C4) — Proteins in the immune system that may be low in some autoimmune conditions.

Who it is for

A primary care clinician, rheumatologist, or other specialist may order this panel when symptoms or exam findings raise concern for an autoimmune disorder.

Preparation

No fasting is usually required for this panel. Tell your clinician about all medicines and supplements you take, because some can affect the results.

Results and what they mean

Results are reported as individual values with reference ranges, and some markers may be positive or negative. A clinician interprets the pattern of results along with your symptoms and history; one abnormal value alone does not confirm a diagnosis. This is general information, not medical advice.
