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.
A derived biomarker is a value that is calculated from other directly measured biomarkers rather than being measured directly in the lab.
Key benefits of Cesium (Cs) testing
- Cesium nuclear and industrial exposure tracking
- radioactive contamination monitoring
What is Cesium (Cs)?
Cesium is an alkali metal with naturally occurring stable isotopes and radioactive isotopes (notably Cs-137, produced by nuclear fission). Urinary cesium reflects environmental or occupational cesium exposure. Measured via ICP-MS.
Why is Cesium (Cs) important?
Stable cesium is relatively low-toxicity; radioactive Cs-137 from nuclear fallout or accidents is the primary health concern. Monitoring cesium provides relevant information for individuals with potential nuclear industry or fallout-zone exposure histories.
What insights will I get?
Your cesium level reflects exposure to environmental or industrial cesium sources. For most individuals, stable cesium exposure is low-concern. Elevated levels in non-industrial contexts may prompt review of environmental or dietary sources.
