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.
