Abstract

In 2017, the Korean Association of External Quality Assessment Service developed a hormone proficiency testing program that comprised 11 test items for hormone I and four test items for hormone II. This program was conducted twice a year using three-level control materials. Data and results of each test item were analyzed by the respective institutions according to the test instruments. The report was prepared by dividing it into a common report that showed the characteristics of the overall participating institutions and an organization-specific report that showed the assessment data of individual institutions. The following statistical data were presented: the number of participating institutions per group, mean, standard deviation, coefficient of variation, median, minimum value, and maximum value. The individual report was composed of a table, histogram, and Levey-Jennings chart showing the statistics for each test item. The results of the assessment of each institution and the statistical data for each classification are presented in a table, and a standard deviation index was provided for both the company classification and classification by instruments. Although the total number of participating institutions and distribution of test instruments were not significantly different from the previous year, the number of participating institutions varied by test item. The coefficient of variation tended to be relatively high for each test item because the concentration of quality control materials was low and the number of participating institutions was small. I believe that these statistical analysis data are useful for analyzing external quality control results of the institutions and selecting an immunoassay test instrument for hormones.
