Power Point Presentation By: Robert Nataf, MD.
The Urinary Porphyrin Profile has been used to assess environmental toxicity in autistic
children with significant issues through elevations of mercury responsive metabolites,
pentacarboxy, precopro and coproporphyrin. Growing evidence supports usefulness
of the urinary porphyrin profile in monitoring of chelation therapy effectiveness, by
showing
in ¾ of cases real reduction in porphyrinuria and not rarely drastic drop in
mercury
compounds, translated in speech and behaviour improvement.
