Summary

This study is testing whether a new blood test can help tell the difference between depression and schizophrenia, and whether it can show if a treatment is working. Researchers will take blood samples and do mental health check-ins with 500 adults over several visits. The goal is to find a biological marker that makes mental health diagnosis more objective.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this blood test could help doctors diagnose depression and schizophrenia more accurately and see if a treatment is working.
What could go wrong
This is an early observational study, not a treatment trial. The biomarker may not prove reliable enough for routine use.
