Had myself tested at Quest Diagnostics (I ordered as allowed, without a physician). ANA was negative and the PFAS result was a test for 9 Chemicals. The over all score (summation) was 3.64 in the Intermediate Range. The literature states "potential risk of adverse health effects". They have a free physician consultation by phone. He told me I had a low score compared to others and especially at me age. Oh, well. I just received my water filtration system to at least clean up the water.
