A new quick experimental lab test could determine in a matter of days whether an antidepressant is actually working.

Researchers from the University of Illinois at Chicago say they have discovered a biomarker for depression.

Right now it can take several weeks for patients and psychiatrists to figure out if an antidepressant is working properly. Scientists have discovered that a single protein in the brain changes its location within a cell membrane when an antidepressant is working. They say that brain change could be identified with a simple blood test. The test still needs to be studied further.
