We are thinking about testing our son for heavy metals and also vitamin or iron defiencies. Where to start? For the heavy metal test do we do hair test, urine test or blood test? Is any test ok or is there something specific that has to be done for ASD. Also re vitamin or iron test again is there a specific test or what do we request? Am considering trying the Behaviour Balance liquid from the Detox People but would be interested to see if there are any deficiencies.
Thanks
