Fluoride details

Fluoride is a mineral found in drinking water, toothpaste, some foods and teas, and certain medicines. Small amounts help protect teeth, but too much over time can affect teeth and bones. This test measures fluoride in serum or plasma to give a picture of your current exposure. It can be used when high intake is suspected, for example from well water, heavy tea consumption, supplements or certain medicines. A higher result suggests greater recent exposure, while a lower result suggests limited intake. Blood fluoride changes with recent intake and kidney function, so it is interpreted alongside your exposure history and sometimes a urine fluoride test.
