    Method Comparison and Bias Estimation Using Patient Samples; Approved Guideline—Second Edition This document addresses procedures for determining the bias between two clinical methods, and the design of a method comparison experiment using split patient samples and data analysis. The purpose of method comparison is to determine the agreement between two or more methods or analyzers measuring the same analyte. The experiment is preferably performed on split samples measured on both methods, and any difference found between the two methods should be interpreted as analytical difference.

    illustrated by the evaluation of the measurement uncertainty for two clinical chemistry measurement procedures – the determination of creat inine in serum (using a chemical analyser) and free catecholamines in urine (a high performance liquid chromatography method). The current accreditation requirements are also discussed.   same method, also called repeatability. In both cases we are concerned with the question of interpreting the individual clinical measurement. For agreement between two different methods of measurement, we ask whether we can use measurements by these two methods interchangeably, i.e. can the method by which the measurement was made be ignored.

    Clinical and Laboratory Standards Institute7 when comparing measurement procedures. Furthermore, when reporting the results of a method comparison study some academic journals, for example the Annals of Clinical Biochemistry8, require that a limits of agreement analysis be included.   Reliability can be estimated by comparing different versions of the same measurement. Validity is harder to assess, but it can be estimated by comparing the results to other relevant data or theory. Methods of estimating reliability and validity are usually split up into different types. Types of .

"In conclusion, this book provides a statistical modeling approach to the comparison of clinical measurements. The modeling aspects will be particularly appreciated by researchers and others mathematically sophisticated, while the computer code at the end of the book will be useful for practitioners wishing to implement the methods.".

"This book sets out to provide an example-based, 'how-to' guide to the comparison of measurement methods in a clinical context. Whilst much material has been published on obtaining and comparing accurate measurements in medical research this will be the first book length treatment of the subject.

In clinical measurement comparison of a new measurement technique with an established one is often needed to see whether they agree sufficiently for the new to replace the old.

Such investigations are often analysed inappropriately, notably by using correlation coefficients. The use of correlation is misleading. An alternative approach, based on graphical techniques and simple calculations, is.que.

If the “limits of agreement” (mean bias ± 2SD) are not clinically important, then one could use two measurements interchangeably. Generalizability to larger populations is facilitated by reporting confidence intervals.
