Although as I mentioned on the iodine thread, you can probably still get a good idea of what your levels are if you reduce that amount significantly. For you I would take 1gram for example. Then collect your urine for the next 3 hours, fill the tube with that, and send it off. Easy peasy!
Thanks for the clarification Joe. I was pretty shocked by the high dose, but found the section where Gaby talks about this method for testing:
Gaby said:Very interesting! That test is pretty reliable to indicate your heavy metal burden. There is a summary in the book "Why Can't I Get Better" by Richard Horowitz on how to measure heavy metal toxicity based on current guidelines and research. Here are some points:
- Horowitz says blood serum levels are not highly reliable unless there had been a recent acute exposure.
- Hair analysis shows elevated levels of heavy metals in some people, but nowhere near the elevated levels that came back on the DMSA urine challenge on the same people. The urine test consistently shows higher levels of mercury, lead, arsenic and other heavy metals when DMSA was used as a provocation agent.
- 30mg/Kg challenge of DMSA (a weight-dependent dose) with a six-hour urine collection yielded superior results to a 24 hour collection with just 500mg of DMSA. The reasoning for this is that only 20% of DMSA is absorbed from the digestive tract and almost all DMSA is cleared by the kidneys in approximately 4 hours.
-Horowitz reports the differences between doing a low dose DMSA challenge with 500mg and the results with a 30mg/kg of DMSA with a six hour urine DMSA challenge. Lead levels went from 9 to 70, and mercury levels went from 1.4 to 9.3 using the higher dosage of DMSA, in the same patient.
- He says that high dose DMSA (30mg/kg) has been safe and well tolerated with only a rare patient reporting nausea, flu like symptoms and a rash if there is an unknown sulfa sensitivity. However, he recommends this "high dose" just for the urine test, to determine your burden of heavy metals. For detox, the very low dose of 100-200mg every two nights or other "low dose" protocol would do just fine. Specially if you are very sick and toxic loaded!
Evil heavy metals!
