History
The company was founded in Berkeley, California, by Jenna Hua, an environmental health scientist and registered dietitian, as part of Y Combinator's Summer 2019 batch.[3] It has since received several Small Business Innovation Research grants from the National Institutes of Health.[4]
Products and services
The company's main product is a mail-in urine test kit that measures 13 biomarkers of EDC exposure, including metabolites of bisphenol A (BPA), phthalates, parabens, and oxybenzone, using high-performance liquid chromatography.[5] After sending in a sample, customers receive a personalized report showing their levels, how they compare to the general population, what health problems those chemicals are linked to, and steps they can take to lower their exposure. For example, a Green Africa Youth activist shared through the Minderoo Foundation that her test report showed “medium” concentrations of plastic-related chemicals compared with other users and national data, and she was advised to avoid fragrance products like air fresheners, perfumes, and candles to reduce exposure.[6]
Research
In 2024, the company's researchers published a study in the International Journal of Environmental Research and Public Health evaluating whether personalized reporting of urinary EDC biomarkers influenced participant knowledge and behavior.[7] They reported increased "environmental health literacy" and reductions in urinary concentrations of monobutyl phthalate, a phthalate metabolite, among participants receiving report-back. In a 2025 study, the research team found that higher use of personal care products was associated with urinary metabolites of phthalates and self-ratings of poor health.[8] The results also suggested women and people who take supplements were at greater risk of EDC exposures.
The company is conducting the Reducing Exposures to Endocrine Disruptors (REED) study in partnership with the Healthy Nevada Project, a 600-participant clinical trial examining the effectiveness of EDC testing and intervention services.[9]
Media coverage
The company was featured in TIME Magazine in April 2024 in an article titled "A Test Told Me I'm Basically Made of Plastic. You Probably Are Too" by journalist Jeffrey Kluger.[10] Similarly, Daily Mail journalists did the test and reported on their results, noting their individual reports advised them to switch to fragrance-free shampoos and store food in glass instead of plastic containers.
In the 2026 Netflix documentary The Plastic Detox, six couples experiencing unexplained fertility problems use Million Marker test kits to measure chemical exposures before and after interventions guided by environmental and reproductive epidemiologist Shanna Swan.[11][12]
