CLSI EP05 Abstract

Clinical and Laboratory Standards Institute document EP05-A3—Evaluation of Precision of Quantitative Measurement Procedures; Approved Guideline—Third Edition provides guidance for evaluating the precision of in vitro diagnostic quantitative measurement experimental designs and includes recommendations for establishing precision performance. Included are guidelines for duration, experimental designs, materials, data analysis, summarization, and interpretation—techniques adaptable for a wide spectrum of measurands and system complexity. These guidelines are intended for manufacturers or developers of clinical laboratory measurement procedures, and for users who wish to determine their own performance characteristics. A balance is created in the document between complexity of design and analysis, and simplicity of operation.
