Objective To ensure the accuracy and reliability of fluoride test results at key monitoring points of endemic fluorosis in the country so as to provide reliable information for monitoring. Methods The results of the determination of 2 kinds of high and low concentration water samples at 20 monitoring points in 20 provinces (cities) in China were analyzed, and the precision and accuracy of the results of each laboratory were evaluated. Results in addition to individual fluorine test results there is a small systematic error, the remaining provinces test the basic quality of qualified. Conclusion The data of fluorine in water outside the monitoring points in all the provinces of China are accurate and reliable, and have practical value
