Abstract
Plasma zinc, copper, and amino acid levels have been measured in a group of autistic children. All three variables were found to be normal. These findings are in disagreement with the previously reported results of some other workers but if confirmed would indicate that autism cannot simply be attributed to a disorder of zinc metabolism.
