Statistical Methods: With Special Reference to Biological Variation

Loh TP and Metz MP, 2015, Am J Clin Pathol, 143, 683-93 , Indirect estimation of pediatric between-individual biological variation data from 22 common serum biochemistries 0270 April 23 2019 2019-09-14 · Biological variation (BV) is expressed as a percentage and intra-individual variation was relatively small while inter-individual was relatively large. Biomarkers with a CV I < 10% for both genders were the percentage of CD3 +, CD4 +, and CD8 + T-cells; and serum concentrations of sCD14, sgp130, and sCD163. The biological importance of measuring individual variation Douglas L. Crawford , Marjorie F. Oleksiak Journal of Experimental Biology 2007 210: 1613-1621; doi: 10.1242/jeb.005454 "Biological Variation, Individual" is a descriptor in the National Library of Medicine's controlled vocabulary thesaurus, MeSH (Medical Subject Headings).Descriptors are arranged in a hierarchical structure, which enables searching at various levels of specificity. The aims of the present study were to determine the intra- and interindividual biological variation of vitamins A, E, B 1, B 2, B 6, C, and K and carotenoids in plasma, whole blood, or erythrocytes from apparently healthy persons and to define quality specifications for vitamin measurements based on their biology. The biological variation (BV) of the human body components examined in laboratory medicine (analytes) can be described as of three types, namely, variation over the span of life, predictable cyclical variation that can be daily, monthly or seasonal in nature, and random variation. The biological variation occurring over a person’s lifetime is related with the physiological changes inherent to growth, aging, pregnancy, menopause, and other normal circumstances. Biological variation – reliable data is essential.
