“ These risks are primarily due to personal contact with infective biological samples and can have serious health consequences, such as infectious hepatitis, and other diseases. There is also some risk from the chemical content of these samples, but this is much less. Those who handle urine specimens should wear protective gloves, and avoid aerosolization of the samples. ”

“ NOTE: Working standards, samples, and blanks must be analyzed under the same conditions, including temperature, for accurate results. Prepare a calibration graph on three-cycle semi-log paper plotting millivolts on the linear scale and fluoride concentration, μg/mL, on the log scale. Maintain standardization by running a standard with every 10 specimens. NIOSH Manual of Analytical Methods (NMAM) , Fourth Edition, 8/15/94 FLUORIDE in urine: METHOD 8308, Issue 2, dated 15 August 1994 - Page 3 of 4 8. Run a spiked urine control specimen with every 10 specimens to maintain quality assurance. ”

“ Prepare at least five working standards in the range 0.1 to 100 μg F /mL by appropriate dilutions of the calibration stock solution with distilled water. Analyze a set of working standards together with the samples and blanks (steps 9 through 12) starting with the lowest concentration. ”
