Ok, a few thoughts.
Direct to consumer lab testing is offered in ~47 states in the country. It has been available for years with thousands of tests available. To date, there has been no apocalypse from empowering consumers to know about their own personal health.
NMS is one of the preeminent toxicology labs in the country. This test is Liquid chromatography–mass spectrometry which is known, quantifiable, extremely accurate and repeatable test methodology.
National Academies of Science, Engineering and Medicine explicitly references this lab in their report. Further, they go on to elucidate the risks and benefits of offering PFAS testing to people.
"Harms of PFAS testing include fear induced by blood draw, a small risk of injury or infection at the draw site, difficulties in interpreting results, and psychological stress that may occur when people who are tested learn that they or their family members have high levels of PFAS exposure. On the other hand, biomonitoring for PFAS blood levels may also alleviate fears associated with not knowing one’s PFAS levels. Another potential benefit is increasing awareness of exposure so that exposures can be reduced. If sources of exposure are identified, actions taken to reduce these exposures, such as using a water filter, may also benefit family members in addition to the person who was tested. Community-level benefits may be associated with PFAS testing as well, such as empowering communities to respond to contamination and providing a baseline with which to evaluate the impact of community-level interventions to reduce exposure. Additionally, biomonitoring for PFAS in the context of epidemiologic studies could provide more information about PFAS-associated health effects."
Also a couple of quotes from the same paper.
"Kristen Mello of Westfield Residents Advocating for Themselves (WRAFT) said to the committee:
You don’t have a problem getting an insurance assessor when your car is hit, you don’t have a problem getting an insurance assessor when you have a tornado, but this slow motion unfolding environmental and public health disaster … is intentionally keeping the information from us so that we cannot take action.
Furthermore, Emily Donovan of Clean Cape Fear, said:
Sadly it feels like guinea pigs are treated better, because at least their exposures are thoroughly studied for the betterment of humanity.
And Cathy Wusterbarth of Need Our Water said:
We’ve tested the fish; we’ve tested the deer; we’ve tested the groundwater, the waterways, and the foam. When are we going to test the people?… The only risk [of testing] is to the polluters who do not want us to link them to our exposure."
Make what you will.
