The Erythrocyte Sedimentation Rate (ESR or Sed Rate) measures how quickly red blood cells settle at the bottom of a test tube. Faster-than-normal settling often indicates inflammation in the body. While it doesn't pinpoint the cause, it's a useful general marker for infections, autoimmune diseases, and inflammatory conditions.
