Empirical age-adjusted ESR upper reference estimate
—
Empirical estimate only; compare with the reporting laboratory's method-specific interval
About
This calculator applies the Miller, Green, and Robinson empirical adult rule for an age- and sex-adjusted upper ESR reference estimate. It is not a laboratory reference interval and does not replace the range reported with an ESR result.
Formula
Interpretation
What the result represents: An empirical upper reference estimate from a published adult population rule.
Input units: Age in completed years; result in millimeters per hour.
Worked example: At age 60, the estimate is 30 mm/hr for males and 35 mm/hr for females.
Applicable population: Adults; the source rule should not be extended automatically to children.
Interpretation limitations: Laboratory method and population matter. ESR can change with anemia, pregnancy, immunoglobulins, age, sex, and many diseases. This estimate cannot establish or exclude inflammation, infection, autoimmune disease, or malignancy.
