Quick answer
An erythrocyte sedimentation rate test, commonly called ESR or sed rate, measures how quickly red blood cells settle to the bottom of a tall, thin tube over a set period. A faster settle can be associated with inflammation somewhere in the body. It is a general marker rather than a specific diagnosis, so results are interpreted with other tests and a provider evaluation.
What this test measures
The ESR test works by measuring the distance red blood cells fall in one hour. Inflammation can cause red cells to clump and settle faster than usual. Many conditions can raise the value, including infections, autoimmune conditions, and some cancers, and the result can also be influenced by age, sex, pregnancy, and anemia. A normal result does not rule out disease.
A blood sample is collected from a vein, usually into a tube containing an anticoagulant. The laboratory reports the result in millimeters per hour and compares it with a reference range that varies with age and sex. ESR is frequently ordered together with C-reactive protein, which is a different marker of inflammation.
People may order this test when a provider is evaluating joint pain, unexplained fever, or other symptoms that could involve inflammation, or when monitoring a known condition over time. Because it is non-specific, ESR is rarely interpreted alone. A qualified healthcare provider should explain what the value suggests in the context of your health.
