ABSTRACT
Objective To investigate the current status of the coefficients variations (CVs) of internal quality control (IQC) data for serum procalcitonin in China.Methods Data had been collected by Web based submission system,the laboratories which enrolled in 2017 serum procalcitonin external quality assessment (EQA) program had attended.The data had includ edthe CVs of two levels of IQC materials (level 1 and 2) in March of 2017 and long-term cumulative in control data.Mi crosoft Office Excel 2007 was used to analyze and process the data,the acceptable rates of CVs were calculated based on the 1/3TEa and 1/4TEa standards.The instruments which was used in laboratory internal quality control system of EQA,were grouped and counted,the acceptable rates of each group was calculated according to two evaluation standards.According to the laboratory detecting system was matched or not,to calculate the proportion of laboratories,and to adapt to the two standards.Results The acceptable rates of the same standards were close and the acceptable rates of level 2 were relatively higher.After grouping according to the instruments,the acceptable rates of each group were uneven.According to the labo ratory detecting system was matched or not,the acceptable rates of the matching system were much more higher.Conclusion To strengthen internal quality control system,and to improve the detection quality level much further.Laboratory should pay more attention to the mission of internal quality control,in order to ensure the reliability of test results.
