Can A Blood Test Predict Suicide?

by Moin Uddin Ahmed Tipu

A small study suggests there may be a biological marker for those who think about or try to commit suicide. Anthony explains this crazy, controversial claim and what it could mean for the way we treat mental illness.

Researchers identify biomarkers for possible blood test to predict suicide risk

“Indiana University School of Medicine researchers have found a series of RNA biomarkers in blood that may help identify who is at risk for committing suicide.”

Predictors of suicidal behaviour found in blood

“Changes in gene expression can indicate heightened risk for self-harm.”

Brain Science Upstages DSM-V, So-Called Mental Health ‘Bible’

“Since the 1970s, the Diagnostic and Statistical Manual of Mental Disorders, has reigned as the so-called “bible” of psychiatry. But now, with the May 22 release of its fifth edition, the DSM-5 is losing some of the support of its faithful.”

The promise and challenges of biomarkers for mental illnesses

“The human brain is the location of personality, emotion, learning and wisdom in a unique individual.”

Biomarkers in psychiatry: drawbacks and potential for misuse

“For more than 20 years, researchers have attempted to identify diagnostic and prognostic biomarkers for psychiatric disorders including schizophrenia, major (unipolar) depression, and bipolar disorder.”

Biomarkers trump behavior in mental illness diagnosis

Here’s how doctors decide which mental or neurological disorder their troubled patients
suffer from: they ask questions like, “Are you hearing voices?” and “Do you feel like people are out to get you?”

Finding Simple Tests For Brain Disorders Turns Out To Be Complex

“If you’re having chest pain, your doctor can test you for a heart attack. If you’re having hip pain, your doctor could test for osteoarthritis.”

anythign  new has a prossiablty to be abused and if it can be it most likely will be. As if it is there then someone will abuse it and companies will use it to charge higher for their service if they are going to cover it becuase it is a marker that you have a higher risk of whatever.

What they could try doing is doing the test on identical twins. I have an identical twin and we both have a genetic predisposition to depression. I have had depression before and my sister never did. By testing us, scientists would be able to tell if they were testing genetic predispositions or if they were finding something else.

crappy study. they need better studies. this sounds important to look at and keep an eye on.

ELISA STRANGEHUMANBEING September 1, 2014 - 2:46 PM

why do they hospitalize people if they want to kill themselves? why cant psychiatrists think about their own business? their lives wont be affected if the person kills himself.

i can understand if the patient is a 12 years old or a their close relative. but a full grown stranger? who the fuck cares?

This is just my opinnion, speaking from someone who have had suicide thoughts, you should not get someone else to decide wether they commit suicide, the person them self needs to do it, you can help them, try and get them out of it, but don't put them in a hospital! Trust me, that only makes it worse, the bad air, bad food, not being able to do what you would normaly do, it's a pain in the arse, it's basicly torture.

It is stupid how people can be so selfish as to say, I like you or "I have feelings for you, there for you may not chooce to love your self, because I love you, you are not alloud to die", this is stupid, but again, there are a big differance between not wanting to live due to bullying, or because you have disabilities, or you are mentaly i'll ect.

A boy who grows up wanting to be a football star, or is running & exersising a lot, and then they get in a car actident where they spend their rest of their life in a wheelchair, they should be allowed to commit suicide because they simply don't feel like their life is worth living.

If you are not doing well socialy, then you will wanna try and help them feel better & get a better life.

And if you have never had suicide, please dont say anything about this comment, good or bad.

Like someone said on here the doctors could care less they get paid either way so why should it bother people when we committe suicide

Wyatt Barriger August 15, 2015 - 2:42 AM

The sample size was too small and didn't represent enough groups of people.

Nelly Frenshaw August 24, 2015 - 1:40 PM

Sickos in the psychiatry industry can't leave anyone who's suffering alone. Just make it worse by drugging people with braincell killing drugs so they can rape the land of money. Psychiatry doesn't care about ANYBODY, they care about MONEY ONLY. They won't be happy until they're reading everyone's mind and everyone is drugged for thought crimes.

Wtf! nah that's some gay shight

Susan Corn January 2, 2016 - 1:02 AM

They need to be concerned also that many disabled are also deemed ill to get treatment from not having a family

Shelly Fu May 22, 2016 - 10:06 PM

Probably got SAT1 gene from doing the SAT lol

Richard Jones October 6, 2016 - 2:34 PM

Psychiatrists dont have a fucking clue…

Crystal Lin November 9, 2016 - 8:03 AM

Why can't you guys say yes or no?

Tamara Ervin February 14, 2017 - 9:54 AM

mental illness affects millions of people, and not all of them think of suicide.

Good for me I love dogs March 3, 2017 - 7:21 PM

if there is, the kids THESE days might need to have it done AT LEAST once a week. There are WAY TOO MANY kids trying to end their lives or ending their lives. Or ending someone else's life and then their own. Or just someone else's. It's almost like it's an epidemic and it's SO SAD.

Mac Daddy the GOAT August 11, 2017 - 4:49 AM

I don't believe this how is that possible..

What about Schizophrenia

Sherlock Gnome July 1, 2018 - 11:30 PM

But they never compared it to people who were not bipolor? How is this is a valid study.

xri xro August 19, 2020 - 6:45 AM

The researchers in Indiana wanted a biomarker to see if someone could be hospitalized for suicide attempts.

They took 9 men with bipolar and checked their blood for similarities.
Then they checked the blood of men who had commited suicide and blah blah blah they found a biomarker gene called SAT1..

They were able to predict if someone would be hospitalized for suicide with 80% rate but again correlation doesn't equal causation and the sample size was about 18 people total who were also only men and there are also many other factors associated with it too.
