Researchers are studying a new blood test that might help doctors better diagnose depression and schizophrenia, and predict which patients will respond well to treatment. The study will collect blood samples from about 500 people at Royal Columbian Hospital who have been diagnosed with depression or are experiencing psychosis or schizophrenia. By looking at specific markers in the blood, the researchers hope to develop a tool that could one day help doctors choose the best treatment for each person.
Currently, doctors diagnose depression and schizophrenia based mainly on conversations and observations, which can sometimes be unclear or take time to confirm. This study aims to create an objective blood test that could make diagnoses faster and more accurate, and help predict which treatments will work best for each person.

You would visit Royal Columbian Hospital's psychiatric clinic three times over the course of the study. At each visit, you would have blood drawn for the new test and complete standard mental health questionnaires. The study tracks you over time to see how the blood markers change and whether they match your symptoms and response to any treatment you receive. There is no medication being tested in this study—it is purely observational, meaning researchers are watching and collecting information rather than treating you with something new.
