Urine Fluoride Analysis in Arizona

What this test measures

Fluoride is a mineral found in water, soil, and many dental products. At appropriate levels it supports dental health, but excessive exposure over time can affect teeth and bones. The body clears fluoride mainly through the kidneys, so urine levels reflect how much has been taken in recently.

The test uses a urine sample, often collected over a defined period or as a spot sample, depending on the laboratory's instructions. The laboratory measures fluoride concentration, and results may be adjusted for creatinine or reported alongside the collection volume to improve interpretation. Sample timing matters because fluoride clears from the body relatively quickly.

Testing may be requested when exposure is a concern, such as in certain occupations or when water sources contain high natural fluoride. It can also be used to monitor exposure in a workplace program. A qualified healthcare provider or program interprets the result with information about drinking water and other sources.
