Question Can levels of perfluoroalkyl and polyfluoroalkyl substances (PFASs) in the blood be reduced by blood or plasma donations?
Findings In this randomized clinical trial of 285 firefighters, both blood and plasma donations resulted in significantly lower PFAS levels than observation alone. Plasma donation was the most effective intervention, reducing mean serum perfluorooctane sulfonate levels by 2.9 ng/mL compared with a 1.1-ng/mL reduction with blood donation, a significant difference; similar changes were seen with other PFASs.
Meaning Blood or plasma donations may be used to reduce serum PFAS levels.
