Considerations for future environmental DNA accreditation and proficiency testing schemes

Proficiency testing/external quality assessment: current challenges and future directions.

BACKGROUND Proficiency testing (PT), or external quality assessment (EQA), is intended to verify on a recurring basis that laboratory results conform to expectations for the quality required for patient care. CONTENT Key factors for interpreting PT/EQA results are knowledge of the commutability of the samples used and the process used for target value assignment. A commutable PT/EQA sample de...

Accreditation of analytical laboratories and proficiency testing: experiences from Thailand on the issues of pesticide analysis.

Thailand, the economic growth of which largely depends on agriculture-based industry, recognizes the importance of international standards for harmonization of international food trade and for protection of human health from chemicals used as food additives or those present as contaminants. Pesticides which are widely used in Thailand are the anticholinesterase pesticides, pyrethroids, coumarin...

Proficiency testing schemes on determination of radioactivity in food and environmental samples organized by the NAEA, Poland

Participation in the interlaboratory comparisons (ILC) and PT schemes is an important tool to assess the laboratory competence. It allows also improving the quality of laboratory routine work and comparing its results with those of other laboratories. It can be also used to verify reliability of the data produced by a laboratory and provide confidence in measurement results to the users of labo...

Hospital accreditation: a certificate of proficiency for healthcare institutions.

National Association for Proficiency Testing

These suggestions are as follows: 1) Regular use of certified reference materials and/or internal quality control using secondary reference materials 2) Participation in interlaboratory comparison or proficiency testing programs 3) Replicate tests or calibrations using the same or different methods 4) Retesting or recalibration of retained items 5) Correlation of results for different character...
