SwabTek

SwabTek is a private U.S. company that develops and sells dry, paper-based presumptive field test kits for narcotics, explosives, and related threat-detection applications. Its products are designed for rapid on-site screening by law enforcement, security personnel, schools, corrections facilities, transportation security teams, and some consumer/home users. The company emphasizes safer handling than legacy liquid-reagent kits by using dry reagents embedded on paper-based test formats. SwabTek markets individual tests for substances such as fentanyl, cannabis, cocaine, heroin, and amphetamines, as well as broader narcotics screens, gunshot residue tests, and explosive detection kits. The business appears to be commercially focused rather than drug-development oriented, with revenue derived from selling test kits and related screening solutions.
