Biological variation is central to all Proteomics. Technical and Intra- and inter-individual biological variability data bank. Different results are usually observed when a quantity is measured in different specimens from the same individual obtained over a time span. For an individual, this variation is due to the imprecision of the measurement procedure, that is to say the metrological variability, as well as Se hela listan på acutecaretesting.org Biological Variation. Biological variation refers to the variance in test results within a single individual over a specified period of time, and between individuals of a defined population. From: Clinical Biochemistry, 2013.

Individual biological variation

As of May 2019, EFLM is managing the new biological variation database. We were honored to host this database for 15 years. Desirable Specifications for Total Error, Imprecision, and Bias, derived from intra- and inter-individual biologic variation Many analytes of interest in the clinical laboratory can vary over an individual's lifetime, simply because of natural biological factors involved in the aging process. These variations may occur rapidly at critical points in the life cycle, such as during the neonatal period, childhood, puberty, menopause, or old age. 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 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, … 2019-09-14 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 1.

Across the biological scales, variation explained by each level varied among leaf traits (Figure 2a). Specifically, variation explained by family varied across traits from 0% to 31.3%. Genus also accounted for a large amount of variation in PL (76.2%) and LMR (58.9%).
