Mental illnesses such as bipolar disorder are very hard for psychiatrists to diagnose sometimes. It's a subjective procedure requiring the patient to tell the professional about his or her symptoms. After that, the doctor must give a judgment which ultimately diagnoses the patient.

But what if medical professionals were able to test the blood and detect whether or not a person had bipolar disorder or depression? This could, theoretically, eliminate the need for subjective judgments on people's mental state. However, some folks believe this is too accurate.

The ethical concerns stem from the fact that ten genes have been shown to reveal a person's mental status. Personality characteristics are controversial in medicine, and a test that can allegedly tell a person if they're unstable could cause a bigger rift. However, if used properly, this seems like a more effective way to treat patients of psychiatry. We'll have to keep an eye on this for future developments!
