The Erythrocyte Sedimentation Rate (ESR) test measures how quickly red blood cells settle at the bottom of a vertical tube over a specified period. Inflammatory proteins in the blood cause red cells to clump together and settle faster. An elevated ESR indicates the presence of inflammation, infection, autoimmune disorders, or chronic diseases. Although ESR does not identify the exact cause, it is widely used to monitor disease activity and response to treatment in conditions such as rheumatoid arthritis, tuberculosis, and chronic infections.
