A blood test may help diagnose depression.
A blood test could make it possible to significantly differentiate patients with depression from those without.
Until now the diagnosis of major depressive disorder, and other psychiatric disorders, had traditionally been based on patients' symptoms. However, the accuracy could vary, depending on the experience of the practitioner and the resources available.
With this test, in which 9 biomarkers are examined, diagnostic precision is increased, and it allows monitoring of the individual response of each patient to treatment.
It also has a 91% sensitivity and a specificity of 81% in the distinction between participants with major depressive disorder and healthy individuals.
