What are the Diagnostic Biomarkers in Psychiatry?

A biomarker attempts to use biological information like proteins in blood, brain waves, or genetics to gather information about a psychiatric condition. This can be information on whether or not someone has a psychiatric illness, if they will develop an illness in the future, or what kinds of therapy they might respond to. These kinds of tests are used frequently for other medical conditions, but it has been difficult to find good tests for use in psychiatric illness.
