The Department of Health and Human Services, specifically the Centers for Disease Control and Prevention (CDC), intends to award a sole source contract to the University of California, San Francisco (UCSF) for urine analysis services related to occupational exposures to illicit drugs in forensic science divisions. The contract aims to analyze urine samples for substances such as cocaine, fentanyl, heroin, and methamphetamine, utilizing UCSF's specialized liquid chromatography-tandem mass spectrometry (LC-MS/MS) technology, which provides the lowest achievable detection limits for these drugs. This procurement is critical for addressing significant gaps in knowledge regarding the health risks faced by forensic science workers who may be exposed to these hazardous substances, with the contract period set from March 1, 2024, to February 28, 2027. Interested parties may submit their interest and capability to respond to this requirement by emailing Laurie Presley at xnp0@cdc.gov by 1:00 PM Eastern Time on November 15, 2024.
