FBI LaboratoryFederal Bureau of Investigation
As one of the largest and most comprehensive forensic laboratories in the world, the FBI Laboratory provides forensic and technical services to federal, state, and local law enforcement agencies at no expense to these agencies. Analyses of physical evidence ranging from blood and other biological materials to explosives, drugs, and firearms are conducted by the Laboratory, which also serves as a continual source of new scientific techniques. Laboratory examiners provide expert witness testimony in court cases regarding the results of forensic examinations, and specially-trained teams of Special Agent and support personnel assist domestic and international law enforcement agencies in large-scale investigations and disasters.
