Investigating poor performance in proficiency testing
Content
A laboratory will occasionally have a poor performance in a PT scheme. When this occurs, the laboratory should acknowledge it, carry out an investigation and document a review of possible causes, even if it decides not to take any specific action. This leaflet, prepared by the EURACHEM Proficiency Testing Working Group, gives advice for laboratories on how to best address such events.
This second edition is an editorial amendment to reference recent guidance on proficiency testing.
The second edition is currently available in English. Links to translations of the first edition, available in 10 languages, are temporarily maintained on this page (below) for convenience while translations of the second edition are prepared.
