I can’t see a toxic issue in those labs.
Fe/Pb: Serum iron levels vary wildly depending on recent meals. I have had some say very low and some very high. So Fe ratios cannot be trusted.
Tests did not cover bromines. Only good way to flush out bromines is high dose iodine. One guy had that happen, it makes you stink, fishy, his wife really noticed. Used to be bromated vege oil in citrus drinks to stabilize citrus oils, that was a big problem. Some meds have bromine and then there is fire retardants.
