Blood test indentifies high suicide risk

Times of India   A simple blood test can now identify people most prone to committing suicide.

Scientists from Indiana University School of Medicine researchers have found a series of RNA biomarkers in blood that may help identify who is at risk for taking their on life.

Researchers said the biomarkers were found at significantly higher levels in the blood of both bipolar disorder patients with thoughts of suicide as well in a group of people who had committed suicide.

Researchers now believe the results provide a first "proof of principle" for a test that could provide an early warning of somebody being at higher risk for an impulsive suicide act.

"Suicide is a big problem in psychiatry. It's a big problem in the civilian realm, it's a big problem in the military realm and there are no objective markers. There are people who will not reveal they are having suicidal thoughts when you ask them, who then commit it and there's nothing you can do about it. We need better ways to identify, intervene and prevent these tragic cases," said investigator Dr Alexander B Niculescu, director of the Laboratory of Neurophenomics at the Institute of Psychiatric Research at the IU School of Medicine.
