The Erythrocyte Sedimentation Rate (ESR) is one of the oldest and simplest tests for detecting inflammation in the body. A high ESR indicates inflammation but doesn't pinpoint the cause — it's used alongside other tests to help diagnose conditions like infections, autoimmune diseases, and inflammatory disorders like rheumatoid arthritis or lupus.
Inflammation and autoimmune biomarkers help identify systemic inflammation, suspected autoimmune disease, and disease activity in known autoimmune conditions.
Anyone with unexplained joint pain, rashes, fatigue, or recurrent fevers; patients with known autoimmune disease monitoring flares; or individuals with strong family history of autoimmune conditions.
