The Department of Defense, through the Defense Health Agency (DHA), is seeking information from qualified vendors for specialized metabolomics analysis services to support ongoing research at the United States Army Medical Research Institute of Environmental Medicine (USARIEM). The procurement aims to obtain both untargeted and targeted metabolomics measurements from various human biological samples, including urine, blood, feces, saliva, and tissue, necessitating advanced laboratory capabilities such as ultra-high performance liquid chromatography-tandem-mass spectrometry (UPLC-MS/MS) and gas chromatography-mass spectrometry (GC-MS). This initiative is critical for enhancing the understanding of metabolic functions and nutritional status within military health studies. Interested parties must submit their qualifications, including business size and capabilities, by January 7, 2025, to Kasey Carroll at kasey.l.carroll.civ@health.mil, as responses are voluntary and will not result in a binding contract.
