Abstract:
Objective:To analyze the assessment results of external quality control of urine iodine in county (city, district) level laboratories in Xinjiang Uygur Autonomous Region (Xinjiang), to evaluate the ability of the laboratories in testing urine iodine, and to provide a reference basis for monitoring of iodine deficiency disorders in Xinjiang.Methods:The Z-ratio scoring method, reference value and uncertainty method were used to analyze and evaluate the results of county (city, district) level laboratories participating in the urine iodine external quality control assessment in Xinjiang from 2017 to 2019.Results:The coverage rates of county (city, district) level laboratories participating in the assessment in Xinjiang from 2017 to 2019 were 53.13% (51/96), 66.67% (64/96), and 67.71% (65/96), respectively, with a feedback rate of 100%. The Z-ratio scoring method had qualification rates of 76.47% (39/51), 93.75% (60/64), and 89.23% (58/65), respectively, with an average qualification rate of 86.48% over the past three years. The qualification rates of the reference value and uncertainty method were 92.16% (47/51), 96.88% (62/64), and 76.92% (50/65), respectively, with an average qualification rate of 88.65% over the past three years.Conclusions:The coverage rate of urine iodine external quality control assessment in county (city, district) level laboratories in Xinjiang has been increasing year by year. Only the standard requirement of achieving a qualification rate of 90% in the 2018 assessment is met, and the average qualification rate over the past three years has not yet reached the standard. The urine iodine detection capability of county (city, district) level laboratories in Xinjiang still needs to be improved.
