Method: ICP-MS (Inductively Coupled Plasma Mass Spectrometry) with creatinine normalization by Jaffe Reaction (CLIA 14D0646470); not cleared or approved by the FDA. Results in µg/g creatinine; reference intervals based on NHANES population data under non-provoked conditions. Not a stand-alone diagnosis; should be interpreted in clinical context.
Uranium is a naturally occurring radioactive metal found in soil, rock, and groundwater with no biological role in humans.
Key benefits of Uranium (U) testing
- Uranium natural and industrial exposure tracking
- drinking water contamination and kidney toxicity assessment
What is Uranium (U)?
Uranium is a naturally occurring radioactive metal found in soil, rock, and some groundwater supplies. Dietary and drinking water exposure is the primary source for most non-occupationally exposed individuals. Urinary uranium reflects recent exposure. Measured via ICP-MS.
Why is Uranium (U) important?
Uranium is both chemically toxic (with kidney as the primary target organ per EPA assessments) and radioactive. Natural uranium in groundwater - particularly in certain geological regions - is a recognized public health concern. Monitoring urinary uranium may be particularly relevant for individuals using private well water or living in uranium-rich geological areas.
What insights will I get?
Your urinary uranium level may reflect drinking water quality - particularly if you use well water - or food grown in uranium-containing soils. Elevated levels may prompt water quality testing and discussion with your care team.
