Abstract:
Objective:To analyze the assessment results of the external quality control and network operation of urinary iodine in local laboratories of Shandong Province, to evaluate the ability of consistent analysis.Methods:In 2016, there were 65 county-level urinary iodine laboratories participated in the provincial external quality control assessment, and there were 124 county-level urinary iodine laboratories participated in the national external quality control assessment in 2017. In 2018, all 137 county-level urinary iodine laboratories in the province participated in the national external quality control assessment. The testing results were analyzed with Z score method (qualified:│Z│≤2; basically qualified: 2 <│Z│ < 3; unqualified:│Z│≥3).Results:The 65 county-level laboratories in Shandong Province were evaluated in the provincial quality control test of urinary iodine in 2016, the feedback rate was 92.3% (60/65), the overall qualified rate was 81.7% (49/60); 124 county-level laboratories in Shandong Province were evaluated in the national quality control test of urinary iodine in 2017, the feedback and qualified rate were both 100.0% (124/124). All the 137 county-level laboratories were evaluated in the national quality control test of urinary iodine in 2018, the feedback and qualified rate were both 100.0% (137/137).Conclusions:The test abilities of urinary iodine in local laboratories of Shandong Province has been increasing continuously, and it has initially reached the detection level required for the full coverage of urinary iodine monitoring in all counties of the province.
