the rapid pace of changing technology is leading to high rate of import and export between different countries. in outsourcing governmental organizations duties to private sectors, it is a need to control sectors and they should be under assessment policy. this research has been developed to show how the accredited laboratories of iranian standard (isiri) can be assessed for their technical ser...

CONTEXT Participation in proficiency testing (PT) or external quality assessment (EQA) programs allows the assessment and comparison of test performance among different clinical laboratories and technologies. In addition to the approximately 2300 tests for individual genetic disorders, recent advances in technology have enabled the development of clinical tests that quickly and economically ana...

Proficiency testing (PT) is pivotal in assessing laboratory qualifications for certification and licensure. PT is expected to typify routine assay performance and determine whether the laboratory is producing clinically useful test results. Conventional schemes use mail-distributed test specimens and are often criticized as measuring the best possible laboratory performance, principally because...

This study investigates the effectiveness of robust estimators location and dispersion, used in proficiency testing listed ISO 13528:2015, outlier detection. The models utilize (a) kernel density plots, (b) Z-factors, (c) Monte Carlo simulations, (d) distributions derived from at most two contaminating one main Gaussian. simulation parameters cover a wide range those commonly encountered (PT) s...

External quality assurance (EQA) or proficiency testing for point-of-care (POC) testing is in principle similar to EQA for larger hospital laboratories, but the participants are different. The participants are usually health care personnel with little or no knowledge of laboratory medicine. The implication of this is that the EQA provider has to a) convince the participants that participation i...

Abstract The Food and Drug Administration’s Veterinary Laboratory Investigation Response Network is comprised of more than 40 animal diagnostic laboratories within North America offers voluntary Proficiency Exercises to these participating laboratories. joint Exercise Program run in collaboration with the Center for safety Nutrition Institute Health, located at Moffett Testing Laboratory.
