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 Platinum (Pt) testing
- Platinum catalytic converter and chemotherapy agent exposure tracking
- platinum-group metal monitoring
What is Platinum (Pt)?
Platinum is a platinum-group metal increasingly detected in urban environments due to catalytic converter emissions. It is also used in platinum-based chemotherapy agents (cisplatin, carboplatin). Urinary platinum primarily reflects environmental or medical exposure. Measured via ICP-MS.
Why is Platinum (Pt) important?
Environmental platinum from catalytic converter road dust has been measurably increasing in urban environments. For most individuals, levels are very low. Individuals who have undergone platinum-based chemotherapy may show elevated urinary platinum for extended periods. Urban air quality and traffic exposure may be relevant factors.
What insights will I get?
Your platinum level may reflect urban environmental exposure from catalytic converter emissions or medical exposure from platinum-based cancer treatments. Most individuals will have very low levels; elevated findings may relate to recent chemotherapy or high urban traffic exposure.
