rtoz writes "Scientists Are Developing A Blood Test To Determine Whether People Are Suicidal.
Last year, researchers in Sweden published a study linking suicide attempts to higher-than-usual levels of quinolinic acid, a neurotransmitter associated with inflammation.
Now, a team of scientists in Australia is using that finding to develop a blood test to measure levels of quinolinic acid in the blood.
The test would function as a diagnostic tool to help doctors gauge a depressed person's mental state--the higher the levels of the chemical, the more likely a patient is to attempt suicide."
