Intramuscular histamine can be used to confirm a diagnosis of schizophrenia in the young schizophrenic male. It will increase his urinary excretion of vanil-mandelic acid significantly. Histamine induced vanil-mandelic-aciduria will neither occur in the non-schizophrenic psychiatric male patient nor in any psychiatric woman patient, schizophrenic or not.
