Erythrocyte Sedimentation Rate
Erythrocytes are red blood cells. The sedimentation rate is the time it takes for your red blood cells to settle at the bottom of a test tube.

Ranges
Each lab publishes a reference range for the population groups it tests, usually the middle 95% of results. These intervals describe that population, not an optimal or healthy target. How ranges differ
Quest Diagnostics, Sed Rate by Modified Westergren 809
| Provider context | Male | Female |
|---|---|---|
| ≤50 Years | ≤15 mm/h | ≤20 mm/h |
| >50 Years | ≤20 mm/h | ≤30 mm/h |
Tests
Check the catalog code, specimen, method and preparation for every test that measures Erythrocyte Sedimentation Rate. Select up to five tests to compare them side by side.

- Method
- Method varies depending on the instrument/reagent used. All methods used correlate well with the Westergren method.
- Collection
- Invert tube immediately eight to 10 times once tube is filled at time of collection.
- Reference notes
- • Male: 0 to 50 years: 0−15 mm/hour, 50 years and older: 0−30 mm/hour • Female: 0 to 50 years: 0−32 mm/hour, 50 years and older: 0−40 mm/hour

Verify these ranges and sources
We compile this page from named laboratory catalogs, guidelines and studies. Labs calculate reference intervals from the people they test, for one assay method and one population group, so an interval describes that population rather than an optimal target.
