The erythrocyte sedimentation rate test is a blood test used to detect inflammation in the body.

Why it matters: It helps screen for inflammatory conditions including autoimmune diseases, blood disorders, infections, inflammatory arthritis and some cancers. It cannot confirm a diagnosis on its own, and a low rate is not usually a cause for concern.
