(ii) Determination of the Assigned Value There are various procedures available for the establishment of assigned values. The most common procedures are listed below in an order that, in most cases will result in increasing uncertainty for the assigned value. These procedures involve use of: d) Known values- with results determined by specific test item formulation (e.g. manufacture or dilution). e) Certified reference value-as determined by definitive methods (for quantitative tests). f) Reference values:- as determined by analysis, measurement or comparison of the test item alongside a reference material or standard, traceable to a national or international standard. (iii) Statistical Evaluation of Test Results Appropriate statistical design of a proficiency testing scheme is essential. Careful consideration is given to the following matters and their interaction. g) The precision and trueness of the test(s) involved; h) The smallest differences to be detected between participating laboratories at a desired confidence level; i) The number of participating laboratories; j) The number of samples to be tested and the number of repeat tests or measurements to be carried out on each sample; k) The procedure to be used to estimate the assigned value; l) Procedures to be used to identify outliers. 3. Benefits of Inter Laboratory Testing The direct benefits of participation of proficiency testing are - It provides an objective means of assessing and demonstrating the reliability of the data they are producing - Laboratories can claim that they can perform testing competently - It supplements laboratories own internal <strong>quality</strong> control procedures by providing an additional external audit of the testing capability - Laboratories can prove their testing capabilities to users that the results produced by them are reliable. The results from proficiency testing programme are useful to the participating laboratories. Successful participation in specific programme may represent evidence of competence for that exercise. Similarly, unsuccessful performance may reflect a random departure from laboratory’s normal state of competence. Participation in proficiency testing programme helps the laboratories to assess and demonstrate the reliability of the data they are producing. One of the main uses of the proficiency testing 97
