Our treatment team administered the test to a 30-year-old woman with a five-year history of schizophrenia who did not accept the fact that she had schizophrenia and who had problems remaining adherent to antipsychotic medications. The test yielded a positive result for the diagnosis of schizophrenia (score of −9199), with a conditional probability score that indicated a 95% chance of having the illness. After being informed of these results, our patient began to accept that her symptoms could be attributed to schizophrenia. For the first time, she expressed interest in learning about schizophrenia, acknowledged a personal connection to her family history of the disorder, and accepted her need of antipsychotic medications. Her therapeutic alliance with her psychiatrist and treatment team has improved, she has enrolled in a college-level class, and her attitude toward antipsychotic treatment remains positive. Her psychiatrist notes that this remarkable change was the result of her confidence in the blood test results—for the first time she had objective data about her illness.
