Köp Statistical Methods, With Special Reference To Biological Variation.

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.

There are two types of biological variations: within-subject and between-subject. Within-subject variation is the random fluctuation around a homeostatic point. In individuals, the homeostatic points usually vary. The variation between individuals is called between-subject biological variation.

Reliability of biological variation data available in an online database: need for improvement. Carobene A. BACKGROUND: Biological variation (BV) data enable assessment of the significance of changes in serial measurements observed within a subject and are used to set analytical quality specifications.

It's just not age- and sex-specific health care service utilization and costs in the western region of Sweden.

Intra- and inter-individual biological variation of 12 amino acids from dried blood spot samples in healthy individuals Variation, in biology, any difference between cells, individual organisms, or groups of organisms of any species caused either by genetic differences (genotypic variation) or by the effect of environmental factors on the expression of the genetic potentials (phenotypic variation). Reliability of biological variation data available in an online database: need for improvement. Carobene A. BACKGROUND: Biological variation (BV) data enable assessment of the significance of changes in serial measurements observed within a subject and are used to set analytical quality specifications. Biological variation has generally been defined as random fluctuation around the homeostatic set point for each individual (within-subject or intra-individual biological variation) and the 2015-03-19 Chance differences in the true and recorded values may result in an apparent association between an exposure and an outcome, and such variations may arise from unbiased measurement errors (e.g. weight of an individual can vary between measurements due to limited precision of scales) or biological variation within an individual (e.g. blood pressure or body temperature, which are likely to vary Individual variation in drug response Prescribers have numerous sources of guidance about how to use drugs appropriately (e.g.

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.

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.

Chapter 6 Preanalytical Variables and Biological Variation Donald S. Young, M.B., Ph.D. The human body is composed of many different compounds and elements; the concentration or activity of these analytes in body fluids may reflect an individual’s health or pathophysiological state. Many factors other than disease may affect the concentration or activity of these analytes.31,49…
