Can anyone please refer me to some good unbiased site that look at the risks and benefits of chelation therapy?
Sorry to blame your doc then; nurses aren't infallible either!
Regarding agendas, DAN doctors generally attribute autism and a range of behavioral irregularities to vaccine reactions and heavy metal toxicity. These conclusions are controversial to say the least. They tend to believe that biomedical interventions "cure" such conditions and are particularly fond of recommending chelation as a magic bullet. For a DAN doctor to find chelation an appropriate remedy for a BLL of 4 is testament to ideology overcoming common sense, and I would consider such a recommendation to be agenda-driven. Obviously DAN doctors are very popular on MDC and quite honestly I don't wish to divert the conversation to a wrangle over DAN and vaccines. As the mainstream medical community recognizes lead exposure and poisoning as a severe problem, I personally see no particular need to seek alternative practitioners given the level of attention, seriousness, and respect given this issue by mainstream medicine.
Neither hair nor urine testing is particularly accurate or helpful in determining the level of lead in the body.
Chelation is controversial. You're not going to find much that you can't point a finger at for being biased one way or another. I hope that the articles below can at least establish for you that chelation is the protocol for lead poisoning only when blood lead levels are much, much higher than your son's (generally a BLL of 45 or over). I'm not interested in scaring people, so I'm not going into this here, but if you want to know the worst of what chelation can do, you can google chelation and death. Bottom line, chelation is something you only want to do when necessary, and then under the care of a reputable board-certified physician.
