  "definition": "1. A study where a centralized study design coordinator sends identical samples to multiple different laboratories for analysis. The resulting raw data are analyzed by the study design coordinator by a given procedure to provide estimates inter-laboratory accuracy, precision, and/or detection limits. {OW/EAD} {OPP} {OAR/OAQPS} {ORCR}\n\n2. An inter-laboratory method validation study is a practical testing of the written method on identical materials, usually derived from split samples, by a number of laboratories. The study is not intended to evaluate laboratories; it is intended to evaluate method reproducibility among laboratories. Deviations from the inter-laboratory study protocol should be strongly discouraged, and any deviations that occur should be documented. Participating in Inter-laboratory Comparison Studies/Programs can be either existing Proficiency Evaluation Programs or Round Robin Studies or a combination of programs and studies to assure evaluation of all laboratory operations.\n\n3. A study where a centralized study design coordinator sends identical samples to multiple different laboratories for analysis.
