No, the phrase "there's no evidence" implies an attempt to find out that resulted in no support for the notion.
But let do some simple math. Let's say I (and a dozen other donors) have 10ng/mL of PFAS in my system and a recipient has 5ng/mL. Assuming 20 pints of blood in a human for the rest of this word problem. Recipient requires a transfusion of 10 pints which happen to be sourced by those 12 donors, What is their PFAS load after the transfusion?
