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.
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 2,4-Dichlorophenoxyacetic Acid (2,4-D) testing
- Chlorophenoxy herbicide exposure tracking
- lawn care and agricultural chemical burden assessment
What is 2,4-Dichlorophenoxyacetic Acid (2,4-D)?
2,4-D is a common broadleaf herbicide used in residential lawn care, turf management, and agriculture. Unlike most chemicals in this panel, 2,4-D is directly excreted in urine without metabolic conversion first. Measured via LC-MS/MS.
Why is 2,4-Dichlorophenoxyacetic Acid (2,4-D) important?
2,4-D is classified as a possible human carcinogen by IARC and is one of the most widely applied herbicides in residential settings. Urinary 2,4-D reflects personal biological exposure - whether from treated lawns, parks, playing fields, or conventional produce.
What insights will I get?
Your 2,4-D level may indicate recent contact with treated lawns, golf courses, parks, or conventionally grown produce. Elevated levels may prompt review of environmental exposure near your home or neighborhood. Increasing organic produce consumption may affect future results.
