New research indicates that there may be a way to predict when someone is contemplating suicide.

FOX News Radio's Joy Piazza reports in this edition of "Housecall for Health":

A blood test could provide a warning when someone is thinking of suicide. Researchers at the Indiana School of Medicine found that test-subjects who were thinking of suicide had changes in their blood. They found the same changes in people who actually had killed themselves. The researchers point out, even if a so-called "bio-marker" for suicide risk is found, the most reliable predictor is still for doctors and therapists to listen closely to what their patients are telling them.
