Blood test may someday help diagnose depression

HealthDay reported, “Depression can be a tough condition to diagnose accurately, but new research suggests that someday a blood test might help,” according to a study published in the journal Molecular Psychiatry.

After giving “a blood test to 36 patients with depression and 43 people who weren’t depressed,” investigators “found that the test correctly identified patients with depression 91 percent of the time; the rest of the time it gave a false-negative diagnosis (it failed to spot the depression).”

In fact, “the test correctly identified patients who weren’t depressed about 81 percent of the time, giving false-positives the rest of the time.”

It still remains unclear, however, “if the test can distinguish patients who have depression from patients who have bipolar disorder,” WebMD points out.

WebMD added that the “new test, called MDDScore, was developed by a company called Ridge Diagnostics,” and it “measures nine indicators in blood called biomarkers that are thought to be altered in adults with major depressive disorder.”

    Thanks for posting this story. I believe we’re in the infancy of understanding mental disorders and that there may be different forms of depression caused by different things (or maybe just different combinations–different ratios–from person to person). I don’t think there’s a one-size-fits-all treatment. Maybe one day blood tests like this will help point people in the right treatment direction.
