In ECAT Newsletter issue 12 a focus article was published about a flowchart for a systematic approach for handling unacceptable EQA results.
Below you can find the original publication from Newsletter issue 10, the flowchart, the corresponding list of notes and the evaluation form to register your investigation of the cause of the error and the undertaken actions (ISO 15189, paragraph 126.96.36.199).
A detailed explanation of the background and the use of the flowchart is published in Biochemia Medica (Kristensen, G.B. and P. Meijer, Interpretation of EQA results and EQA-based trouble shooting. Biochem Med (Zagreb), 2017; 27: 49-62). Below you will find a link to download this publication free-of-charge.
