I'm wondering about the timeing of getting a hair test after having
amalgams removed. Is this going to be a false positive?

I had 3 amalgams removed and replaced with composities on October
15th. I still have 8 remaining that I plan to have removed and
replaced in 3 more sessions if my Dentist will do it. But I'm
wondering if getting a hair test done about 3 weeks after having
amalgams removed will interfere with test and give me a false
positive? I just ordered the test but haven't recieved the kit yet.
Do I need to wait and if so for how long? I also received a hair cut
around that time so my hair is still pretty short in the area the
suggest to get samples from. I want to get tested, but I want to do it
right.

Thanks,
Mike
