ASSESSMENT OF IN VITRO RESEARCH QUALITY BASED UPON INTERLABORATORY COMPARISON TESTS

The article describes the process of interlaboratory comparison tests conducted pursuant to the international quality standards including GOST ISO/IEC 17025 and ISO/IEC 17043, as well as the participation of the Test Center “Center for Radioecological Research” (branch office “Institute of Radiation Safety and Ecology” (hereinafter referred to as IRSE of RSE NNC RK) in such comparison tests. The participation experience in the national and international comparison test programs arranged by such providers as ‘TC Agrostandart – XXI century’ Ltd, ‘Ekogidrokontrol’ Ltd and ALMERA (IAEA) is also described 2020 through 2024. Measurement means, procedures, regulatory documents and a list of research objects and indicators to be determined are presented within the scope of interlaboratory comparison tests.

Particular attention was paid to measurements obtained by the Test Center and their analysis by means of a statistical |Z|-score, which allows for the determination of the conformity degree of results and providers’ established standards. The participation in interlaboratory comparison tests makes it possible for the Test Center not only to prove its competence but also verify the result repeatability, calibration reproducibility and to reveal problem areas associated with measurement techniques, personnel\s qualifications or equipment calibration. The intercomparison measurements have demonstrated the accuracy and operational robustness of the Test Center, which proves the qualification and correct application of the test techniques in the field of radioecology and chemical analysis.
