The average US citizen has a large load of PFAS in their blood[1] from clothing, carpet, water and other sources. The levels have dropped a great deal in the last 20 years but it's unlikely you've increased your levels much beyond what you already had from other sources.
The blood serum levels reported by CDC are staggering. As an example, I have a well and it's in a contamination plume of PFOS and PFOA. The EPA certified laboratory measured level two years ago was 11 ppt (parts per trillion.) The CDC measured 2.1 ug/L of PFOA (only) in the blood of over 2000 people in 2014. That's 2,100,000 ppt; 5 orders of magnitude higher than my 'contaminated' water.
