Not sure if it counts as non invasive, but I've read research suggesting donating blood lowers pfas levels reliably (not too mention other potential benefits that are not particularly well validated).

is that really a solution? you're just giving someone else the PFAS. fixes you temporarily, fucks up someone else

If someone needs blood transfusions they have larger concerns than PFAS (that's likely at a similar baseline anyway).
