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 Tin (Sn) testing
- Tin dietary and industrial exposure tracking
- canned food and solder monitoring
What is Tin (Sn)?
Tin is a metal used in food can coatings, solder, alloys, and some chemical compounds. Dietary exposure is primarily from canned foods - particularly acidic foods in tin-coated cans. Urinary tin reflects recent systemic exposure. Measured via ICP-MS.
Why is Tin (Sn) important?
Inorganic tin has relatively low toxicity; organic tin compounds (tributyltin, etc.) are more concerning but less common in consumer exposure. Tin levels may reflect frequency of canned food consumption, particularly acidic canned products.
What insights will I get?
Your urinary tin level may reflect canned food consumption or contact with tin-containing materials. Elevated levels may prompt review of canned food intake frequency and sourcing.
