NCT ID NCT06856161
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
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.
