Id also advise against.
I had this 'Kelmer' test myself 2 years ago with 9 amalgams in. My body ached all over for a week after!
[Result was 606% increase, whatever that means].

The fact u have learned about the danger of mercury means its really not relevant *exactly* how much u have been exposed to since filling placement.
If and when u get these damn things out, u will be exposed to even more during the process, so id recommend focusing on doing everything possible to limit [and prepare for] *that* exposure.
