I-phenytoin RIA kit is described to provide the statistical data of assay performance.
The following statistical data and charts of a quality control were calculated from results of measuring sixteen assays. They are: the average banch coefficients of variation(ABCV); the relationships of error and dose-response(RER); the precision profile (P. P) and the parameters of standard curve. Using the ANOVA procedure
the between-assay and within-assay precisions were also counted. The quality control charts and two-sample Youden charts were made to evaluate the between-assay and within-assay drift. This counting procedure is adapted to clinical laboratories
as well as to serve as references for the computer engineers who plan to design a computer program of a quality control of RIA to monitor error in routing assay.
