Summary
Biological variation data shows significant diversity between and within subjects. Existing applications for setting metrological goals require re-evaluation due to this variability.
Area of Science:
- Biomedical science
- Metrology
- Statistical analysis
Background:
- Biological variation is a critical factor in interpreting health data.
- Previous studies highlight substantial differences in biological variation within and between individuals.
- Understanding this variation is essential for accurate health assessments.
Purpose of the Study:
- To analyze the diversity of within-subject and between-subject biological variation.
- To assess the implications of this diversity for current metrological applications.
- To advocate for a re-evaluation of metrological goals based on biological variability.
Main Methods:
- Systematic review of previously published works on biological variation.
- Comparative analysis of within-subject and between-subject variation data.
- Evaluation of existing frameworks for setting metrological goals.
Main Results:
- Significant heterogeneity was observed in biological variation data across diverse studies.
- The extent of variation differs considerably between individuals and within the same individual over time.
- Current metrological goals may not adequately account for this observed biological diversity.
Conclusions:
- The wide diversity in biological variation necessitates a critical review of its application in setting metrological goals.
- Existing metrological requirements may need revision to accommodate the complex nature of biological variability.
- Further research is needed to develop robust methods for incorporating biological variation into metrological standards.
