A normal sed rate, or erythrocyte sedimentation rate (ESR), varies depending on an individual's age and sex. This test measures how quickly red blood cells settle to the bottom of a test tube in an hour.
Normal Sed Rate Ranges by Age and Gender
The typical ranges for a normal sed rate are generally higher for older individuals and for females. Here's a breakdown of the normal ranges:
| Gender and Age Group | Normal Sed Rate (mm/hour) |
|---|---|
| Males younger than 50 | 0 to 15 |
| Males older than 50 | 0 to 20 |
| Females younger than 50 | 0 to 20 |
| Females older than 50 | 0 to 30 |
It's important to note that these values represent general guidelines. A sed rate outside of these ranges does not automatically indicate a specific condition, but it can signal the presence of inflammation or other medical issues that may warrant further investigation by a healthcare professional.
