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 Palladium (Pd) testing
- Palladium dental and catalytic converter exposure tracking
- platinum-group metal monitoring
What is Palladium (Pd)?
Palladium is a platinum-group metal used in dental restorations, catalytic converters, electronics, and jewelry. Urinary palladium reflects recent exposure, most commonly from dental work or occupational contact. Measured via ICP-MS.
Why is Palladium (Pd) important?
Palladium from catalytic converters contributes to road dust and urban environmental exposure, with studies showing measurable palladium in urban populations. Dental palladium alloys may leach over time. The toxicological profile of long-term low-level palladium exposure is an area of ongoing study.
What insights will I get?
Your urinary palladium level may indicate dental restoration exposure, urban catalytic converter-related environmental exposure, or occupational contact. Elevated levels may prompt review of dental materials or occupational environment.
