Key benefits of Monoethylphthalate (MEP) testing
- Diethyl phthalate exposure tracking
- personal care product chemical burden assessment
- hormonal pathway monitoring
What is Monoethylphthalate (MEP)?
MEP is a urinary metabolite of diethyl phthalate (DEP), a plasticizer found in fragrances, personal care products, and flexible plastics. Detected in urine via LC-MS/MS and normalized to creatinine.
Why is Monoethylphthalate (MEP) important?
Phthalates may disrupt hormonal signaling pathways. MEP is among the most commonly detected phthalate metabolites in adults and primarily reflects exposure from fragranced personal care products rather than dietary sources.
What insights will I get?
Your MEP level may indicate recent diethyl phthalate exposure. Elevated levels may suggest high-frequency use of fragranced products such as lotions, shampoos, and colognes. Serial testing may reveal whether switching to fragrance-free alternatives reduces your chemical burden over time.

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.
