Abstract
Objective To introduce a method of judging detection analysis of the performance of clinical acceptability. Methods Based on the Westgard method evaluation decision chart to establish the mathematical Cartesian coordinate system, the imprecision for the X-axis, bias for the Y-axis to get three total error of judgment line TE = bias +2s/3s/4s linear equation of functional,analysis of the relationship between operating point and three linear position, could determine the detection method to analyze the acceptability of the performance. Results The Westgard method evaluation decision chart was divided into poor,marginal,good,excellent,four types. Operating point was accepted only in good or excellent performance,mathematical function analysis to determine the analytical performance of the detection method. Conclusion The application function analysis of the relationship between points and straight lines to determine the analytical performance of the detection method than using squared paper plot point out of the operating point analysis method performance is easy to operate,fast and practical.关键词
