I did it but only because my son tested high for lead and arsenic. A reputable doctor should first do a test to see if you child even needs chelation. Basically you give him one dosage and then collect his urine for 24 hours. The urine is sent to a lab and tested. If the urine has high metals, then your son needs chelation. A responsible doctor will do this test first because chelation is hard on the body.

If I may. When considering chelation therapy, you have to consider that there are two versions. If the theory holds that a child's neurological deficits are a result of heavy metal deposits in the brain, then your doctor's heavy metal toxicity tests (which they can run on serum, urine, and hair samples) will be low and they will conclude that your child does not need chelation therapy because they do not have heavy metals in their body. But that is not true. Heavy metals are supposed to be excreted by the body. Excretion takes place in the urine and hair mostly. But if the heavy metals are being deposited in the brain, then they are not being excreted. Hence the low heavy metals being detected in urine and hair samples. Serum heavy metal levels will indicate free-floating heavy metals in the blood. Again, if they are deposited in the brain they will not be floating around in the blood.

Most chelation therapy (including hemodialysis) will bind the heavy metals that are free floating and even those that are built-up in the liver. But, unless you have a mechanism to draw the heavy metals across the blood-brain barrier, standard chelation therapy will largely be ineffective in eliminating heavy metal deposits in the brain.

Dr. Michael Goldberg has some disturbing brain scan pictures in his book "The Myth of Autism" showing damage to certain areas of the brain in his autistic patients who had previously tried chelation compared to other autistic patients who had not done chelation. I personally found those images concerning enough so that I will not try chelation for my DD (and our particular biomed doctor does not perform chelation because he also feels the risk/benefit ratio is not favorable).
