Abstract:

Objective To investigate the current application status of reference intervals for dry chemistry items in China,and compare with current health industry standards and draft for approval. Methods By Web-based external quality assessment(EQA) software system,the submitted data from the laboratories, which attended national reference interval investigation for dry chemistry and routine chemistry,2014,were collected. Statistical methods,such as single-sample t determination,were used to analyze the data. Results A total of 83.3%(30/36)of reference interval upper and lower limits had differences compared with those from health industry standards(P<0.05),and 83.3%(20/24)of male and female reference interval upper and lower limits had significantly statistical differences compared with those from health industry standards(P<0.05). The 73.6%(53/72)of measurement system reference interval upper and lower limits had significantly statistical differences compared with those from health industry standards(P<0.05).Conclusions The reference intervals for dry chemistry items in China have overwhelmingly big differences compared with health industry standards. It is proposed that the reference intervals for dry chemistry items in China should be established for Chinese population.
