What causes a low Erythrocyte Sedimentation Rate (ESR)?
Normal range ≤ 20 (age/sex-dependent) mm/hr (0-20 mm/hr SI). Specimen: Whole blood (EDTA). See the full Erythrocyte Sedimentation Rate (ESR) reference page for critical values and nursing considerations.
What is the normal range for Erythrocyte Sedimentation Rate (ESR)?
The standard teaching reference range for Erythrocyte Sedimentation Rate (ESR) is ≤ 20 (age/sex-dependent) mm/hr in conventional units, or 0-20 mm/hr in SI units. This value is measured in whole blood (edta).
| Specimen | Whole blood (EDTA) |
|---|---|
| Conventional range | ≤ 20 (age/sex-dependent) mm/hr |
| SI range | 0-20 mm/hr |
