Does Objective Diagnostic Criteria Matter in Psychiatry?

One of the criticisms antipsychiatry folks like to make of psychiatry is its lack of objective diagnostic criteria. In other words, there’s no blood test that says you have bipolar disorder or schizophrenia.

And this is true. While today we do have blood tests for biological markers indicative of mental illness diagnosis, there is no hard and fast test that can diagnose a psychiatric disorder (except Huntington’s, for which we have discovered a gene).

The fact of the matter is no matter what is written in the Diagnostic and Statistical Manual of Mental Disorders (DSM) or what blood we draw or which scans we do nothing diagnoses a person properly except a trained psychiatric professional.

But that doesn’t mean there’s nothing objective or meaningful about it.
