Urinary Bisphenol A (BPA)
Synthetic chemical monomer used in polycarbonate plastics and epoxy resin can liners that functions as a potent environmental xenoestrogen.
Standard vs. Optimal Reference Rangesug/g Cr
Standard reference intervals represent the statistical 95% distribution of unselected commercial populations. Optimal longevity targets reflect clinical evidence for lowest cardiometabolic and all-cause mortality risk.
Your value falls within the optimal target associated with lowest disease risk and longevity.
<1.5 ug/g Cr
General reference distribution across unselected commercial populations.
<0.5 ug/g Cr
Concentration target associated with minimal all-cause cardiometabolic mortality.
Molecular Mechanism & Clinical Purpose
Binds nuclear estrogen receptors (ER-alpha and ER-beta) and membrane GPER, disrupting endogenous steroid signaling and adipogenesis.
Differential Diagnosis
Elevated Levels (BPA High)
- •Consumption of canned foods/beverages with epoxy linings
- •Handling thermal paper receipts
- •Microwaving plastic food containers
Low Levels (BPA Low)
- •Use of glass, stainless steel, and BPA-free food storage
- •Optimal phase-II hepatic glucuronidation

Pre-Analytical Caveats & Diagnostic Workup
Pre-Analytical Considerations:
Specimen collection should follow standardized phlebotomy protocols. Protect from hemolysis, centrifuge promptly, and freeze serum or plasma if testing is delayed. Patient should be in a resting, fasting state where indicated.
Reflexive Testing Protocol:
- Confirmatory testing and secondary biomarker quantification for BPA
- Targeted organ system imaging or functional dynamic testing related to xenoestrogen & endocrine disruption
- Comprehensive baseline metabolic, renal, and inflammatory assessment (CMP, CBC, hs-CRP)
