Eat only small wild fish. If it fits in your pan, it is probably okay. 7) Blood tests are relatively worthless for analyzing mercury toxicity, unless you have had a significant recent exposure or eat a lot of sushi or tuna. 8) Hair tests only check for mercury from fish, not from fillings so they only give you a partial picture. 9) The only way to find out your total body load of mercury is to take a medication with sulfur molecules that binds to the mercury like fly paper. This is called DMSA or DMPS. This test should ONLY be done by a trained physician and involves taking one dose of this medicine, followed by a 6- or 24-hour urine collection to see how much comes out. (In my opinion, the most reliable testing is done by Doctorsdata.com). 10) If you are toxic and sick, you may consider addressing your dental health by seeing a biological dentist who can safely help you deal with mercury in your mouth. via Mercury: Get This Heavy-Metal Poison Out of Your Body – Dr. Mark Hyman.
