A laboratory developed test named VeriPsych™ has been released that uses a small sample of a patient's blood to aid in the diagnosis of schizophrenia. [Rathus,1991] The test measures 51 blood-based biomarkers and compares that profile to a biomarker pattern derived from patients that have been medically diagnosed with schizophrenia, resulting in a probability score indicating the likelihood of a patient being positive for the disease.[ Becker T,2006]

Genetics, early environment, neurobiology, psychological and social processes appear to be important contributory factors; some recreational and prescription drugs appear to cause or worsen symptoms. Current psychiatric research is focused on the role of neurobiology, but this inquiry has not isolated a single organic cause. As a result of the many possible combinations of symptoms, there is debate about whether the diagnosis represents a single disorder or a number of discrete syndromes. Despite the etymology of the term from the Greek roots skhizein ( "to split") and phren, phren- ( "mind"), schizophrenia does not imply a "split mind" and it is not the same as dissociative identity disorder—also known as "multiple personality disorder" or "split personality"—a condition...
