Abstract
- All measurements are imperfect and have many potential sources of variation. * An estimate of measurement uncertainty (MU) provides an interval of values within which the true value is believed to lie with a stated probability, and is therefore a quantitative indication of the reliability of a measurement. * MU estimates are essential for assessing whether methods are suitable for clinical use and for comparison of results of a similar type. * MU estimates can help identify method limitations and opportunities for improvement.
摘要
所有测量都是不完美的，并且有许多潜在的变异来源。
测量不确定度（MU）的估计提供了一个值的区间，在该区间内，真实值被认为以规定的概率存在，因此是测量可靠性的定量指标。
MU估计对于评估方法是否适用于临床使用以及比较类似类型的结果至关重要。
MU估计有助于识别方法的局限性和改进机会。
