Specific laboratory studies for brief psychotic disorder do not exist. The history, the physical examination, and laboratory tests can help differentiate brief psychotic disorder from psychotic disorder secondary to general medical condition, delirium, and various other disorders. Routine and specific laboratory work may be needed to exclude other causes of psychoses.
Substance-induced psychotic disorder, substance-induced delirium, and substance intoxication can be distinguished from brief psychotic disorder by considering onset, course, urine drug screening, and blood alcohol levels.
No imaging studies are required to diagnose brief psychotic disorder. Further testing with modalities such as computed tomography (CT), magnetic resonance imaging (MRI), and electroencephalography (EEG) may be considered, but such studies are useful only for diagnosing possible medical causes of the psychosis.
