Abstract:
Objective:This paper analyzed the operation of network laboratory and external quality control assessment of endemic arsenic disease laboratories at all levels in Guizhou Province, to provide reliable experimental quality assurance for evaluating the prevention and treatment effect and taking targeted intervention measure of endemic arsenic poisoning.Methods:The results of network operation and external quality control (arsenic in water, arsenic in urine) were statistically analyzed from 2008 to 2017. The assessment scope included the arsenic detection laboratory of provincial (1), municipal (1) and county level (2) which undertook endemic arsenic poisoning monitoring tasks.Results:From 2008 to 2017, 1 provincial laboratory for the determination of arsenic in water and urine was qualified. From 2011 to 2017, 1 municipal laboratory for the determination of arsenic in water and urine was qualified. From 2014 to 2017, 2 county level laboratories for the determination of arsenic in water and urine were qualified. From 2014 to 2017, the water and urinary arsenic in provincial, municipal and county laboratories had been continuously assessed as all qualified. The │Z│ values of water arsenic in provincial laboratories from 2008 to 2017 and urine arsenic from 2009 to 2017 were ≤2, and the results were satisfactory. The │Z│ values of arsenic in water after 2010 and in urine after 2011 in municipal and one county level laboratories were ≤2, which were all qualified and the results were satisfactory.Conclusions:The network laboratory of endemic arsenic disease in Guizhou Province operates well. The quality control of the laboratory and the results of external quality control of arsenic samples meet the quality requirements of the national laboratory, which can provide accurate and reliable test data guarantee for the continuous elimination of endemic arsenic disease.
