This guidance may help for sample collection, but wouldn't fully address the whole chain of custody. If the test equipment or handling tools/processes in the lab expose the samples to PFAS, then the test is botched. And this is challenging because PFAS are so prevalent and ubiquitous.

Don't get me wrong, I would love to have a test available for PFAS levels. However I've previously been denied a test from the medical provider due to the issues I've outlined above. So I think it would be helpful to know if/how they have addressed this problem.
