Method: LC-MS/MS (Liquid Chromatography/Tandem Mass Spectrometry) with creatinine normalization by Jaffe Reaction (CLIA 17D0919496); not cleared or approved by the FDA. Results reported in µg/g creatinine. Not a stand-alone diagnosis; should be interpreted in clinical context.
Bisphenol S (BPS) is increasingly used as a BPA replacement in plastics, thermal paper, and consumer products marketed as "BPA-free.
Key benefits of Bisphenol S (BPS) testing
- BPA substitute exposure tracking
- emerging bisphenol burden assessment
- identifies hidden exposure in BPA-free products
What is Bisphenol S (BPS)?
BPS is a chemical substitute introduced into many BPA-free plastics, thermal papers, and some food packaging. Like BPA, it is absorbed through the gut and skin and excreted in urine. Measurable via LC-MS/MS.
Why is Bisphenol S (BPS) important?
BPS replaced BPA in many products based on assumed safety differences, but research suggests it may share some biological properties with BPA. Monitoring BPS alongside BPA provides a more complete picture of total bisphenol exposure.
What insights will I get?
Your BPS level may indicate whether switching to BPA-free products has shifted your bisphenol exposure profile rather than eliminating it. Comparing BPA and BPS levels over time may identify dominant bisphenol sources in your personal environment.
