Fluoride, Random details

Fluoride is a mineral found in drinking water, toothpaste, some foods and teas, and certain medicines. Your kidneys remove much of the fluoride you take in, so its level in urine reflects recent exposure. This test measures fluoride in a single random urine sample. It can help when high intake is suspected, for example from well water, heavy tea drinking or supplements, or when monitoring known exposure. A higher result suggests greater recent intake, while a lower result suggests limited exposure. Because a random sample can be more or less concentrated, results vary with hydration and timing, and are interpreted alongside your exposure history and sometimes a blood fluoride test.
