ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the uncertainty of measurement result of urinary fluoride and to provide quality assurance for determinations.</p><p><b>METHOD</b>The investigation was conducted, according with principles and methods for uncertainty evaluation.</p><p><b>RESULTS</b>The uncertainty of the combined standard of present method was 2.86 %. For the sample containing 4.47 mg/L urinary fluoride, the expanded uncertainty was 0.26 mg/L.</p><p><b>CONCLUSION</b>The uncertainty of the present method was mainly from the sample repeatability, the preparation of standard solution, the linearity of the calibration curve and instruments and so on.</p>
