Blind verification of elevated platelet autoantibodies in serum of schizophrenic patients--part II: adult subjects.

Background: In our preceding study, we assayed in a blind fashion the blood sera of young normal subjects and schizophrenic patients for levels of platelet autoantibodies (PAA). The recorded PAA titers of the schizophrenic patients were significantly higher than those of the normal subjects. This observation has lent support to this test being used as an objective evaluation of schizophrenia in young subjects in the future.
