What if you could determine someone's likelihood of committing suicide by administering a simple blood test?
A new study out of Indiana University suggests it's not that far-fetched.
"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," Dr. Alexander B. Niculescu in a press release.
The researchers have found a series of RNA biomarkers in blood they believe may identify people at risk of taking their own lives.
What's more, the markers are also much higher in blood samples taken from people who later committed or attempted suicide.
Still, the researchers caution this test should only be used in conjunction with other tools such as psychological tests and socio-demographic checklists.
"Over a million people each year worldwide die from suicide and this is a preventable tragedy," said Niculescu.
