Researchers at the University of North Carolina are decoding blood samples taken from recent trauma victims at civilian emergency rooms. They're sequencing genetic material, RNA, DNA and other types of molecules, to identify biological markers for PTSD.
University of North Carolina's Dr. Sam Maclean explains, "The blood is such a valuable tool to use to better understand what's going on with post-traumatic stress, because, after traumatic event, the brain communicates with the body via the blood."
The hope is that if a blood test or DNA can reveal a Veteran has PTSD, then it will reduce the stigma attached to speaking up. When you remove the human element and are able to point to an accurate objective test result, it changes the game.
