The Louisiana State Police Crime Laboratory is a part of the Louisiana Department of Public Safety and Corrections. Since its inception in 1937. the Louisiana State Police Crime Laboratory has been committed to providing the highest quality of professional forensic services to the State of Louisiana. This commitment includes applying sound scientific principles in all analyses, being responsive to our customers, conducting our operations in a fair and objective manner, and being a leader in advancing forensic science. The mission of the laboratory is to assist local, state, and federal law enforcement agencies in Louisiana in the investigation of criminal activity by providing accurate and timely scientific analysis of items of physical evidence and reporting the results of those analyses to appropriate entities in the criminal justice community. Forensic scientists at the laboratory perform scientific examinations of evidence and can provide assistance in the actual collection of evidence at crime scenes when requested.

Laboratory personnel also provide expert testimony in criminal court on their findings, when requested. Analyses performed at the laboratory are often the definitive factor in proving the guilt or innocence of persons charged with criminal acts. Being the largest laboratory of its kind in the state, the Louisiana State Police Crime Laboratory has been utilized by many agencies, both law enforcement and judicial, for the quick and successful resolution of criminal investigations.

The Louisiana State Police Crime Laboratory is accredited by the American Society of Crime Lab Directors/Laboratory Accreditation Board (ASCLD/LAB). The Crime Lab is accredited in the forensic science testing disciplines of controlled substances, trace evidence (fire debris, impression evidence, and general physical analysis), biology, latent prints, toxicology, firearms and toolmarks (including serial number restoration), and crime scene.
