Abstract:
Objective:To analyze the external quality control assessment results of salt iodine, urine iodine, and water iodine in iodine deficiency disorders (IDD) laboratories at all levels in Shandong Province, and provide reliable quality assurance for monitoring and prevention of IDD.Methods:The external quality control assessment of salt iodine, urine iodine and water iodine in provincial, municipal and county levels IDD laboratories in Shandong Province from 2017 to 2021 were conducted, and feedback rate and qualification rate were calculated.Results:From 2017 to 2021, the feedback rates and qualification rates of external quality control assessment of salt iodine, urine iodine and water iodine at provincial and municipal levels IDD laboratories in Shandong Province were all 100.0%. The feedback rates of county level laboratories participating in the salt iodine external quality control assessment were all 100.0%. The qualification rate in 2021 was 99.3% (135/136), and the other four years were all 100.0%. The feedback rates of county level laboratories participating in the urine iodine external quality control assessment were all 100.0%. The qualification rates in 2017 and 2021 were 98.4% (122/124) and 97.1% (132/136), respectively, and the other three years were all 100.0%. In 2021, the county level laboratories in Shandong Province participated in the water iodine external quality control assessment for the first year, and the feedback rate and qualification rate of 69 laboratories were both 100.0%.Conclusion:From 2017 to 2021, the detection capacity of IDD laboratories at the provincial and municipal levels in Shandong Province remains at a high level, and the detection capacity of salt iodine and urine iodine in some county level laboratories still needs to be further improved.
