Summary
This study establishes new reference ranges for erythrocyte sedimentation rate (ESR) in elderly individuals. A novel age-adjusted algorithm is proposed to determine the upper limit of normal ESR values for both men and women.
Area of Science:
- Gerontology
- Clinical Biochemistry
- Hematology
Background:
- Erythrocyte sedimentation rate (ESR) is a common blood test.
- Establishing age-specific reference ranges is crucial for accurate interpretation in elderly populations.
Purpose of the Study:
- To define a reference range for erythrocyte sedimentation rate (ESR) in elderly individuals living in the community.
- To develop and propose a new age-adjusted algorithm for determining the upper limit of normal ESR.
Main Methods:
- Random selection of 194 elderly subjects.
- Analysis of erythrocyte sedimentation rate (ESR) values.
- Correlation analysis with fibrinogen, hemoglobin, and albumin levels.
Main Results:
- Mean ESR values were 4.1 mm/hr for men and 7.2 mm/hr for women.
- ESR values ranged from 0-44 mm/hr.
- Significant correlations were found between ESR and fibrinogen, hemoglobin, and albumin levels.
Conclusions:
- A new algorithm for age-specific ESR upper limits is proposed: Females ESR = Age/3 + 10, Male ESR = Age/3.
- These findings provide updated reference ranges and a predictive tool for elderly populations.
