Patent ID: 8420308

Claim:
A method for diagnosing schizophrenia in a subject, the method comprising the steps of: a. obtaining a blood sample from said subject; b. isolating lymphocytes from said blood sample; c. infecting said lymphocytes with Epstein Ban Virus (EBV); d. determining the cellular basal respiration through mitochondrial complex I enzyme in said EBV-transformed lymphocytes; e. adding an inhibitor of cellular respiration to the EBV-transformed lymphocytes; f. determining the percent (%) inhibition of said cellular basal respiration through complex I in said EBV-transformed lymphocytes in the presence of said inhibitor; and g. comparing said percent (%) inhibition of said EBV-transformed lymphocytes from said subject with the percent (%) inhibition of the cellular basal respiration through complex I in the presence of said inhibitor in EBV-transformed lymphocytes from a nonnative person, wherein a higher percent (%) inhibition of cellular respiration through complex I enzyme in said EBV-transformed lymphocytes from said subject as compared to the percent (%) inhibition in EBV-transformed lymphocytes from said normative person is indicative of schizophrenia in said subject.
