About test
What does Erythrocyte Sedimentation Rate (ESR) measure?
The erythrocyte sedimentation rate (ESR) test measures how quickly red blood cells settle in a tube over a set period. A higher rate can be associated with inflammation in the body, but it is not specific to any one condition. Healthcare professionals may use ESR to help evaluate symptoms such as persistent fever, joint pain, or unexplained fatigue, and to monitor inflammatory conditions over time. Results are interpreted alongside symptoms and other tests.
