Test Code
SynonymsSodium Fluoride
Container TypeLeakproof plastic urine container, no preservative. Do not use glass container.
Supply Item Numberpicture1387
Specimen TypeRandom urine
Preferred Volume5 mL
Emergency Minimum Volume2.2 mL
Collection ProcedureSampling time is prior to shift or end of shift for industrial monitoring. Inorganic analytes with timing "end of shift" (meaning the last two hours of exposure) or "prior to next shift" are eliminated rapidly with a half-life less than five hours. Such analytes do not accumulate in the body and, therefore, their timing is critical only in relation to the exposure and postexposure periods.

NotesUse: Monitor chronic exposure to fluoride.

Additional Information: BEI are reference values intended as guidelines for evaluation of occupational exposure. BEI represent biological levels of chemicals that correspond to workers with inhalation exposure equivalent to the threshold limit value (TLV) of the chemicals. TLVs refer to the airborne concentrations of substances and represent conditions under which it is believed that nearly all workers may be repeatedly exposed, day after day, without adverse health effects.
