cheap heavy metal tests...anybody know of any out there

I'm trying to take out my mercury fillings. But i don't want to do this if i'm not in an overload of heavy metal. I eventually do want them out but right now i just thing a few other things are more important.

Nevertheless, if i do have alot of heavy metals inside me then i would be more motivated to take more glutathione and take out those mercury fillings.

Does anybody know of any ACCURATE tests that are affordable out there?

Thanks

Carlos

Happy Thanksgiving Love you guys!!!!
