Where can i get hair tested for mercury exposure from vaccines, or is that a bogus scam?

Bogus as...: ...A three-dollar bill. Mercury was taken out of children's vaccines almost 10 years ago, and autism rate is higher in mercury-free children than it was in the generation that got the most mercury ever. Also, large fish such as tuna is a much greater source of mercury than vaccines were even when they had mercury in them. And there is no quality control for hair analyses for heavy metals.
