I only skimmed, but if I understand correctly, they sent samples of known PFOS/PFOA levels to numerous labs. Had the labs analyze using their normal method (which could differ lab to lab), and then reported out the results. Results varied lab to lab, sometimes significantly. Would be curious to hear your thoughts on this. Certainly industry may use this as a reason to question our results.
