The histamine test in schizophrenia.
The cutaneous response to intradermal injection of 50 micrograms of histamine was studied in nonmedicated schizophrenic patients, schizophrenic patients treated with neuroleptic drugs, nonschizophrenic patients receiving neuroleptics, and nonmedicated controls. The diminished response previously reported in schizophrenic patients was not reproduced. Thus, the histamine test does not appear to be useful in diagnosing schizophrenia.
