A fluoride urine test measures the amount of fluoride in your urine. It is used to check recent fluoride exposure and help evaluate whether levels are within a normal range. It may be ordered when someone has symptoms or risk factors for too much fluoride.
What it measures
- Urine fluoride concentration — The amount of fluoride in a urine sample, usually reported in milligrams per liter (mg/L).
- Creatinine (sometimes) — A substance that helps adjust fluoride levels for how concentrated your urine is.
- Collection volume (sometimes) — The total amount of urine collected over a set time, if a 24-hour sample is used.
Who it is for
This test is typically ordered by a doctor or dentist when someone has been exposed to high levels of fluoride or has symptoms that could be related to fluoride. It may also be used in workplace or environmental health evaluations.
Preparation
No special preparation is usually needed. Your doctor may ask you to avoid fluoride-containing products, such as toothpaste or mouthwash, for a short time before the test. Follow any specific instructions you are given.
Results and what they mean
Results are reported as a number that your clinician compares with a reference range. A single result may not show the full picture, so your doctor will interpret it along with your history, symptoms, and other tests. This information is general and not medical advice.
