Medically important errors
| Глоссарий по стандартизации, контролю и управлению качеством |
Used here to indicate errors that, when added to the inherent imprecision and inaccuracy of a measurement procedure, cause the quality requirement to be exceeded. medically important random errors are those increases in the standard deviation of the measurement procedure that cause the error distribution to exceed the quality requirement (see critical random errors). medically important systematic errors are those shifts in the mean of the error distribution that cause the error distribution to exceed the quality requirement (see critical systematic error).

Imprecision, английский
- “the random dispersion of a set of replicate measurements and/or values expressed quantitatively by a statistic, such as standard deviation or coefficient of variation.” [clsi] ifcc has recommended that the mean value and number of replicates should also be stated, and the experimental design described in such a way that other workers can repeat it. this is particularly important whenever a specific term is used to denote a particular type of imprecision, such as within-run, within-day, day-to-day, total, or between-laboratories.
- Неточность. см. precision (прецизионность).
- Неточность ров частиц, осаждаемых на каждом предметном стекле, зависит от диаметра отверстия и скорости движения газа.
- Неточность. см. precision — точность.
Inaccuracy, английский
- "numerical difference between the mean of a set of replicate measurements and the true value. this difference (positive or negative) may be expressed in the units in which the quantity is measured, or as a percentage of the true value" [ifcc]. we use the term biasmeas to describe the average systematic difference between a measurement procedure and a comparative method and express it in percent on opspecs charts..
- Неточность, погрешность
- Неточность
- Неточность; погрешность
Measurement, английский
- Set of operations having the object of determining a value of a quantity (1)
- Измерение. система мер.
- Измерение; замер
- The size, length, etc. of something which has been measured
- Измерение
- Обмер
- Оценка
- Измерение dust ~ измерение концентрации пыли
- Измерение. комплекс операций, имеющих целью определение значе-ния величины [32].
- The process of ascertaining the attributes, dimensions, extent, quantity, degree or capacity of some object of observation and representing these in the qualitative or quantitative terms of a data language. any empirical pursuit that places the observer outside his object of observation must consider measurement the fundamental process through which scientific constructs or models are linked to reality (->index, ->symptom). otherwise measurement is only one section in a circular process of computing a stable form. the traditional levels of measurement are nominal, ordinal, interval and ratio scales.
- The magnitude of the property of an object calibrated against one or more units of measure.
- Измерение. комплекс операций, имеющих целью определение значения величины [32].
Requirement, английский
- Требование
- Something which is necessary one of the requirements of the position is a qualification in pharmacy. res abbr reticuloendothelial system
- Требование; спрос; потребность; условие ~ of continuity требование (обеспече- 469 requirement ния) неразрывности [неразрезность сплошности] ~s of structural safety требования техники безопасности в строительстве
Distribution, английский
- Распределение. размещение.
- Распределение - рыночный процесс, при котором крупные рыночные трейдеры в основном продают бумаги мелким трейдерам;
- The distribution of a set of numerical data is how their values are distributed over the real numbers. it is completely characterized by the empirical distribution function. similarly, the probability distribution of a random variable is completely characterized by its probability distribution function. sometimes the word "distribution" is used as a synonym for the empirical distribution function or the probability distribution function. if two or more random variables are defined for the same experiment, they have a joint probability distribution.
- Refers to the spread and shape of a frequency curve of some variable. a histogram is one way to graphically display the distribution of test results by showing the frequency of observations on the y-axis versus the magnitude on the x-axis. the normal or gaussian curve is one form of a distribution.
- Распределение
- Торговля; сфера обращения; распределение
- A way to limit where your usenet postings go. handy for such things as for sale messages or discussions of regional politics.
- The movement of freshly mixed concrete toward the point of placement, either by motorized tools or by hand. distribution-bar reinforcement, distribution
- N дистрибуция complementary ~ дополнительная дистрибу- ция, отношение дополнительности5 contrastive ~ контрастная, контрастирущая дистрибуция non-contrastive ~ неконтрастная, неконтра- стирущая дистрибуция distribution(al)
- Распределение dna (deoxyribonucleic acid)
- Распределение. 1. распределение данных. данные могут иметь определенную форму (вид) распределения, которая зависит от их характеристик. например, рост имеет нормальное распределение (см. normal distribution), а результаты метания игральных костей следуют равномерному (случайному) распределению. 2. распределение (распространение) вещества и его метаболитов в организме после применения препарата. обычно описывается с помощью объема распределения (см. volume of distribution) и свободной фракции.
- Diamond pattern
- A payout of cash or property from a corporation to a shareholder.
- Распределение; размещение; распространение; разводка (труб) ~ of bending stresses over the cross
- Распределение. ранжирование значений переменной от наименьшего до наибольшего и результирующая совокупность характеристик или показателей, выстроенных в виде графика [20]. плотность распределения, например, показывает возможные значения параметра в зависимости от числа появлений каждого значения в выборке или совокупности. во многих случаях это характеризует разброс единич-ных значений выборки или совокупности вокруг среднего значения.
- The delivery of electricity to the retail customer’s home or business through low voltage distribution lines.
- The spatial range of a species, usually on a geographic but sometimes on a smaller scale, or the arrangement or spatial pattern of a species over its habitat. • food resources will lead to this distribution. d. over space: • altitude: species diversity less abundant in higher than lower altitudes. • latitude: ecosystems are more complex in equatorial regions than in higher latitudes (poles) • scale: the greater the sample the better interpretability. • spatial: • aggregated or clump d.: individuals form one or more clumps, attracted to areas with the greatest availability of food or shelter and avoiding less hospitable terrain. • random d.: individual spacing would be determined by chance. • regular or uniform spacing d.: individuals may also be drawn together by some social interaction, such as mating or parental care. in other cases, antagonistic interactions between individuals or scarce d. over time: • habitat: (see there). • succession (see there).
- The transport of low voltage electricity. this connects the transmission network with the majority of electricity consumers. the process is overseen by a distribution network operator. management of distribution is a natural monopoly due to the economies of scale inherent to it. reeep / sustainable energy regulation network – august 2004 - revised september 2010 4
- The set of values of a variable together with the probabilities (->probability) associated with each. a tabulation of the frequencies of tokens by types.
- The process of managing the flow of goods and services from the producer to the customer.

Method development, английский
Refers to the process of formulating the materials, conditions, and protocol for measuring an analyte. method development is mainly carried out by industry. laboratories may make minor modifications to methods to improve performance, in which case, the modified methods should be subject to more rigorous testing and evaluation by the laboratory.
Medical decision level, decision level, xc, английский
A concentration of analyte where medical interpretation is critical for patient care. there may be several different medical decision levels for a particular analyte. xc should provide guidance for selecting relevant estimates of stable imprecision, stable inaccuracy, and matrix inaccuracy. this is analogous to identifying a critical target value (tv) for assessing test performance and validating qc design.
