Erythrocyte Sedimentation Rate

The Erythrocyte Sedimentation Rate (ESR) is a blood test that measures how quickly red blood cells settle at the bottom of a test tube over an hour. When there's inflammation or infection in the body, certain proteins cause red blood cells to stick together and settle faster. Thus, a higher ESR indicates more inflammation, which can help doctors identify or monitor various conditions like infections, autoimmune diseases, or other inflammatory disorders. The test itself is simple, painless, and used alongside other assessments for a clearer picture of your health.
