When selecting a chelating agent for treatment purposes, making an informed choice is critical and the question frequently asked is: which chelating agent is best? We thus evaluated and compared the binding ability of DMPS, DMSA, EDTA, Na-thiosulfate, Alpha-Lipoic Acid. Our aim was to identify which of the chelators would be most useful for the chelation treatment of which metal. While our previous study indicated that for single or multiple metal exposures, the intravenous application of DMPS seemed best suited as a provocation test, this follow-up study demonstrates that other chelating agents may be equally or more suitable. Our data also demonstrates that oral application can be an alternative to the use of intravenous chelation.
