Sed rate, or erythrocyte sedimentation rate (ESR), is a blood test that can show inflammatory activity in the body. Many health problems can cause a sed rate test result to be outside the standard range. A sed rate test is often used with other tests to help your health care team diagnose or check the progress of an inflammatory disease.

When blood is placed in a tall, thin tube, red blood cells, called erythrocytes, gradually settle to the bottom. Inflammation can cause the cells to clump together. Because these clumps are heavier than individual cells, they settle to the bottom more quickly.

The sed rate test measures the distance red blood cells fall in a test tube in one hour. The farther the red blood cells have fallen, the greater the inflammatory response of your immune system.
