"Blood tests measuring PFAS can help doctors manage risks for patients who have been significantly exposed to the chemicals—but the tests cost up to $600, and insurance generally doesn’t cover them.

“Patients with high levels of PFAS, have a higher risk of certain diseases,” including increased cholesterol and certain cancers, said Rachel Criswell, a primary care physician with Redington-Fairview General Hospital in Skowhegan, Maine.

Yet some of her patients decline PFAS tests, she said. “They can’t afford them.”"
