Key takeaways:

  • Campbell Neurosciences validated a saliva-based test to predict suicidal ideation.
  • Previous serum biomarker data was used to create the test.
  • It is the first biology-based test to predict suicidal thoughts.

A saliva-based test from Therapeutic Solutions International’s spin-off company Campbell Neurosciences successfully predicted suicidal ideation, according to a press release.

The test is “the first biological-based system to help predict individuals at risk of this modern-day epidemic,” Kalina O’Connor, president and CEO of Campbell Neurosciences, said in the release.

The test was developed using data from a previous clinical trial using blood biomarkers. Specifically, the trial evaluated cytokine levels in 10 people with no history of suicide, 10 people with suicidal ideation and 10 people with suicidal ideation who attempted to take their own life. According to the release, cytokine levels were positively associated with suicidal ideation and behavior.

“The prospects of a simple saliva-based test will allow for a more personalized approach to regenerative psychiatry, which in the end will result in more lives saved,” Timothy Dixon, president and CEO of Therapeutic Solutions International, said in the release.
