Abstract:
Objective To compare the current application status of reference intervals in dry chemistry to the reference inter-vals of anlytes of wet chemistry in the same hospital.Methods By using web-based external quality assessment (EQA) software system,collecting the submitted data from the laboratories which attended national reference intervals investigation of reference intervals of analytes in dry chemistry and wet chemistry,using professional statistical software for analyzing the data,including paired-samples t test and Yates’Chi-square test.Results 231 laboratories submitted their investigation re-sults including the reference intervals of 23 analytes of dry and wet chemistry.69.6% (32/46)of reference intervals of ana-lytes in dry chemistry have significant statistical differences compared with the wet chemistry in paired-samples t tests. 80.4% (37/46)of medians of reference intervals of analytes in dry chemistry had significant statistical differences in loca-tions and distributions compared with medians of reference intervals of wet chemistry in the same institute.Conclusion The reference intervals of analytes of dry chemistry have differences compared with the wet chemistry in the same hospital.The medians of reference interval’s lower and higher limits of dry and wet chemistry have difference in locations and distribu-tions.Proposed to create our own reference intervals of dry chemistry in China.
