This legislation mandates the Secretary of Veterans Affairs to initiate a study exploring the efficacy of RNA sequencing in diagnosing post-traumatic stress disorder (PTSD) among veterans. The study, to be conducted through the Department's Center for Innovation for Care and Payment, will specifically investigate whether RNA sequencing can effectively identify inflammation or cellular stress, which are recognized symptoms of PTSD. The Secretary is directed to carry out this research within medical facilities located in five different Veterans Integrated Service Networks (VISNs) across the country. The study is set to commence within 120 days of the bill's enactment and will conclude its data collection and analysis by September 30, 2027 . A comprehensive report detailing the study's findings and conclusions must then be submitted to the Committees on Veterans' Affairs of both the Senate and House of Representatives by September 30, 2028 .
