Evaluation of Measurement Uncertainty of 2 2 Clinical Chemistry Assays
摘要
Abstract
Objective To calculate the measurement uncertainty of clinical chemical analytes according to the internal quality control (IQC)and external quality assessment (EQA)data in clinical laboratory.Methods Collected the IQC data from January to June 2013 and EQA data between 2012~2014 of clinical chemistry in clinical laboratory.Calculated the measure-ment uncertainty and extended uncertainty according to the Nordtest criteria.Results It was effective to evaluate the uncer-tainty using IQC and EQA data.ALP ranked the highest extended uncertainty and Na+ ranked the lowest uncertainty.The range of uncertainty varies greatly,electrolyte 4.27~18.16,enzyme 8.12~24.88,small molecular 4.88~12.44,protein and lipids 4.78~13.1.Conclusion The evaluation of clinical chemistry uncertainty by IQC and EQA data is simple and practi-cal,which is beneficial for assurancing the measurement accuracy.关键词
