Curious about your exposure to HORMONE-DISRUPTING CHEMICALS?


Million Marker lets people measure their exposure to environmental chemicals like BPA and phthalates through a mail-in urine test.


Why Test?

Bisphenol-A (BPA) and phthalates are known endocrine-disrupting chemicals (EDCs). EDCs look similar to the hormones in your body and can disrupt normal hormonal functions. For example, BPA mimics estrogen and phthalates block testosterone. Reducing exposure to EDCs is a healthy choice for everyone.


Pregnant or want to get pregnant?

Here are some facts:

EDCs have been linked to reduced fertility in both men and women.

These chemicals can pass through the placenta and breast milk from mother to child.

Early-life exposure to EDCs has been linked to developmental delays and behavioral problems in children.


Trying to detox?

Did you know:

EDCs have been linked to weight changes, diabetes, autoimmune disorders, and breast cancer and other cancers.

Chemical pollutants are present in food and everyday products, such as cosmetics and household supplies.

Some people are more susceptible than others to the potential effects of EDCs, because of individuals’ genetics and other factors.


Just curious or concerned?

Some food for thought:

EDCs have no business being in your body. They add no value and can cause harm.

Unlike for other chemicals, such as lead or mercury, there are no established safe levels for BPA and phthalates.

Knowing your exposure level can empower you to make changes in your lifestyle, move the science forward, and influence policy.


Our Test


What are we testing for in urine?

Our urine test measures your near-term exposure for bisphenol-A (BPA) and phthalates through their metabolites.

The levels detected in urine are typically indicative of exposure in the 24-48 hours prior to collecting the sample. While your urinary BPA level reflects short-term exposure, it is also likely an indicator of daily habits including diet, choices of consumer products and lifestyle.



What can we tell you?

In addition to the level of BPA and phthalate metabolites found in your urine sample, we tell you how your level compares to that of other people. We also provide you with curated information on common sources of exposure, the latest scientific findings on these chemicals and personalized lifestyle recommendations for minimizing your exposure.

What can I do with this information?

What you measure, you can change.

Knowing your own exposure level contextualized and personalized with other information is a practical way for understanding how everyday choices of products, food and environment are impacting your health.


Our Process

Easy pee-sy.


Our Story

Million Marker - DDay-76.jpg

Our overall cumulative environmental exposures i.e. the exposome, are responsible for as much as 70% of chronic disease risk.

Yet if you ask your doctor what you can do about this, chances are they won’t know what to tell you beyond general guidance on eating right and exercising. While this may be generally the right advice, it is neither very personalized nor is it very helpful, especially if you are doing those things already.

There are tests that you can order today that give you very specific information about your genetics and ancestry, which you can do nothing to change. Yet there are shockingly few tools available that let you understand which environmental chemicals your body has been exposed to and what you can do about it. 

We have asked ourselves questions about how our environment and everyday choices impact our health.



We created Million Marker to answer questions like these and many more. Our mission is to crowdsource bio-monitoring to help people understand what’s in their body that shouldn’t be there and how to minimize their exposures.

 The Human Exposome

You are exposed to several chemicals in your daily environment — through the food and water you consume, the air you breathe, the products you use and other lifestyle factors. These exposures to environmental chemicals begin from the moment you are conceived and continue throughout your life. Your exposome is a measure of all your exposures (environment and lifestyle) over your lifetime. It interacts with your genome (genetic information) to determine your health. Given the same environmental exposures, people may respond differently depending on their genetic make-up.

Million Marker utilizes targeted metabolomics (study of small molecules that are involved in metabolism) and personal exposure analysis to allow individuals to measure and track their own exposures over time. Starting with a few biomarkers of environmental exposures, our vision is to discover over a MILLION MARKERs to inform and improve individual health outcomes and advance precision medicine.
