Sed rate erythrocyte sedimentation rate
Print
Overview
Sed rate, or erythrocyte sedimentation rate (ESR), is a blood test that can reveal inflammatory activity in your body. A sed rate test isn't a stand-alone diagnostic tool, but it can help your doctor diagnose or monitor the progress of an inflammatory disease. When your blood is placed in a tall, thin tube, red blood cells (erythrocytes) gradually settle to the bottom.

Inflammation can cause the cells to clump. Because these clumps are denser 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 descended, the greater the inflammatory response of your immune system.

Also, they can help confirm a diagnosis of certain conditions, including: Giant cell arteritis Polymyalgia rheumatica Rheumatoid arthritis A sed rate test can also help determine the severity of your inflammatory response and monitor the effect of treatment. Because a sed rate test can't pinpoint the problem that's causing inflammation in your body, it's usually accompanied by other blood tests, such as the C-reactive protein (CRP) test.
