At-home PFAS and toxin testing

Helping everyone live healthier lives in the face of toxin exposure

We are constantly exposed to toxic chemicals like PFAS in our everyday lives. This is especially true for firefighters, first responders, and people in potentially hazardous professions. Our at-home tests help you track your exposure to these chemicals over time.

We deliver minimally invasive PFAS blood tests from our CLIA-certified lab. The test can be taken in the comfort of your own home using our micro-sampling kits.

Supporting First Responders

First responders perform one of the most challenging jobs in the world. Many risks they face are obvious, but others are hidden. One of the biggest is from constant exposure to toxins and PFAS  during their career.

Helping those who help us

First responders face unique health challenges due to the rigors of their profession. Our mission is the relentless pursuit of better health and fitness outcomes for first responders. As part of this, we will donate a proportion of every sale we make to organizations that help first responders.

Future Developments

Our research and development team is working closely with first responders to develop additional tests. Our aim is to make toxin testing easy, fast, convenient, and available wherever and whenever it is needed, for anyone impacted by environmental or occupational toxin exposures.

What are PFAS chemicals?

PFAS (per-and poly-fluoroalkyl substances) are a large family of man-made “forever chemicals”. They have many useful properties, such as being non-stick and able to repel water or grease. They are used in fast food wrappers, nonstick cookware, waterproof clothing and many other places.

Are PFAS compounds dangerous?

Mounting evidence links PFAS exposure to significant adverse health outcomes. These include several forms of cancer as well as reproductive health issues and organ damage among others. As a result, it is important to understand which PFAS substances are present in your body and in what quantities.

What other toxins does Relentless Health look for?

We are developing tests to identify exposure to compounds that are frequently released in smoke from structural and wildland fires. These compounds are often highly toxic and are absorbed through the skin as well as by breathing. However, they can be hard to detect as they. Our approach offers the potential to do reactive testing on-site at major disasters. 

What will my results tell me?

Each test includes a guide with recommendations on how to reduce PFAS exposure at home and in the workplace.

The Relentless Health PFAS test is designed as a research tool to help you monitor your exposure to PFAS in your environment. It is not intended for use as a clinical diagnostic test. The test results will allow you to monitor your own exposure. Relentless Health is working to establish baseline levels across the population.
