Erythrocyte Sedimentation Rate (ESR), also known as sedimentation rate or “sed rate,“ is a common blood test that measures the rate at which red blood cells (erythrocytes) settle at the bottom of a vertical tube over a specific period of time. It's a non-specific indicator of inflammation and is often used as a diagnostic tool to help healthcare providers identify and monitor various medical conditions. Here's how the ESR test works: 1. Sample Collection: A blood sample is taken from the patient, usually from a vein in the arm. 2. Test Procedure: The blood is placed in a tall, thin tube called a Westergren tube. The tube is then placed in an upright position, allowing the red blood cells to settle over time. 3. Measurement: The ESR is measured in millimeters per hour (mm/hr) and indicates how quickly the red blood cells settle to the bottom of the tube. The higher the rate of sedimentation, the higher the ESR value. The ESR test is not a diagnostic test on
