• Researchers have identified blood biomarkers that can predict suicidal ideation and future hospitalization for suicidality, offering a new tool for risk assessment.
• The study used a multi-cohort approach, including discovery, validation, and testing phases, to ensure the robustness of the identified biomarkers.
• Pathway analysis revealed that these biomarkers are involved in key biological processes related to psychiatric disorders, providing insights into the underlying mechanisms of suicidality.
• The findings support the development of personalized treatment strategies based on an individual's biomarker profile, potentially improving outcomes for those at risk.
