What is an inter laboratory comparison

A proficiency test enables to evaluate the reliability of the services of your laboratory.A inter laboratory comparison (or proficiency test or PTP or round robin test) consists in testing the same samples by different laboratories and in comparing the results.What is an inter laboratory comparisonA proficiency test enables to evaluate the reliability of the services of your laboratory.A inter laboratory comparison (or proficiency test or PTP or round robin test) consists in testing the same samples by different laboratories and in comparing the results.Unity Interlaboratory ProgramUnity Interlaboratory Program Unity Interlaboratory Program An Effective Tool for Evaluating Analytical Performance Clinical laboratories account for a small percentage of overall healthcare budgets,but have a tremendous impact on medical decisions (1,2).Since every reported test result may impact a

THE IMPORTANCE OF INTERLABORATORY

Interlaboratory studies serve several needs and aspects of the quality management of measuring to help the participating laboratory to assess the accuracy of its test results. Results of a proficiency testing program can be used for determination of measurement ofTA265 thermal conductivityAn interlaboratory test program was conducted to determine the precision and bias of ASTM Method E1952 for specific heat capacity and thermal conductivity by modulated temperature differential scanning calorimetry.Results were received from 15 laboratories usingSome results are removed in response to a notice of local law requirement.For more information,please see here.Previous123456NextReport of an interlaboratory comparison organised byReport of an interlaboratory comparison organised by the European Reference The assessment of the measurement results was undertaken on the basis of value obtained after applying the robust statistics to the participants test results,using ProLab software [9].9.Target standard deviation

PROGRAMS AND ANALYTICAL METHODS FOR THE U.S.

An interlaboratory-comparison program is used to assess analytical results from three or more laboratories,which routinely analyze wet-deposition samples from the major North American networks,to determine if comparability exists between laboratory analytical results and to provide estimates of the analytical precision of each laboratory.PROFICIENCY TESTING GUIDELINES ON THE LEVEL OF seek confirmation for confidence in their results and organize quality control procedures for monitoring the validity of performed tests.This monitoring includes the participation in interlaboratory comparisons or proficiency testing programs.In this document,the termPROFICIENCY TESTING AND INTERLABORATORYKeywords proficiency testing,laboratory,interlaboratory comparison s 1.INTRODUCTION Proficiency testing is a method of checking laboratory testing performance by means of an inter-laboratory test.It is an important way of meeting the requirements of ISO/IEC 17025 in the area of quality assurance of laboratory results.

Alternative Performance Assessment

Alternative Performance Assessment Proficiency testing (PT) is the determination of laboratory testing performance by means of interlaboratory comparisons.The CAP Laboratory Accreditation Program (LAP) requires enrollment in PT for many tests/activities/analytes (waived,non-waived,regulated,and non-regulated testing).ASTM C802-141.2 This practice is not intended for use in programs whose purpose is to develop a test method or to assess the relative variability of two or more test methods.Refer to Practice C1067 for procedures to evaluate the ruggedness of a test method.2014 Continuing Compliance Master Series Bestparticular test,the laboratory must perform and document an alternative assessment method semiannually to assess its analytic performance for that test.Alternative assessment may include o Participation in a PT program (graded or educational) o Split sample analysis with reference or
