Key benefits of Thorium (Th) testing
- Thorium radioactive metal exposure tracking
- nuclear and industrial monitoring
What is Thorium (Th)?
Thorium is a naturally occurring weakly radioactive metal found in some minerals, soils, and building materials. It has been used in gas mantles, some industrial applications, and historical medical procedures. Urinary thorium primarily reflects occupational, industrial, or environmental exposure. Measured via ICP-MS.
Why is Thorium (Th) important?
Thorium is a radionuclide with long-term radioactive decay potential. Occupational exposure in nuclear, mining, and some manufacturing industries is the primary concern. Environmental exposure from thorium-containing soil and rock is a lower-level background source.
What insights will I get?
Your thorium level may indicate environmental background exposure or occupational contact. Elevated levels in the absence of known occupational exposure may reflect regional geological thorium concentration in soil and water.

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.
