Battelle Scientists Identify Potential Early Biomarker for Autism Spectrum Disorder.

What is most interesting to me about this article is that porphyrins are also used to diagnose heavy metal toxicity.

Urinary porphyrins testing is a medically recognized way to test for mercury.  There are specific porphyrinsthat spill for mercuryand specific ones that spill for lead.

  • Precoproporphyrin = mercury toxicity. You will not have any levels of Preco unless you have been exposed to mercury.
  • Precoproporphyrin/Uroporphyrin ratio >2 = mercury toxicity
  • Coproporphyrin elevated compared to % Precoproporhyrin  elevation = another metal present like arsenic or lead
  • Elevated Precoproporhyrin/Uroporphyrin = means mercury is the dominant metal
  • Precoproporhyrin/Coproporphyrin ratio lower than reference range when Coproporphyrin is elevated=either lead or arsenic is present

So science is caught once again proving a connection between autism and heavy metal toxicity, but ever so carefully sidestepping the issue of a direct relationship that might actually assist parents in getting the help they need.

Good thing this is something we can do ourselves.
