The laboratory currently services the St. Louis County Police Department, nearly ninety municipal police agencies within St. Louis County, as well as several federal agencies. The laboratory is tasked with providing scientific analyses of physical evidence for these agencies while also offering training of a scientific nature to officers in the law enforcement community. Forensic scientists at the lab use specialized skills to identify, evaluate, and objectively describe evidence from crime scenes, generate reports of these findings, and testify to the results for the judicial system.

The crime laboratory offers forensic services in the following categories of testing: Body Fluid Identification, Nuclear DNA, Controlled Substances, Fire Debris, Explosives, Firearms and Toolmark Examination, and Impression Evidence. The Photography Unit of the crime laboratory stores digital images and makes prints upon request. 

In order to assure compliance with national testing standards, the Biology/DNA section gained accreditation through the National Forensic Science Technology Center (NFSTC) in 2004. In 2005, the St. Louis County Crime Lab was awarded and has maintained accreditation through the American Society of Crime Laboratory Directors - Laboratory Accreditation Board (ASCLD/LAB). This

accreditation covers the areas of Controlled Substances, Trace Evidence (Fire Debris/Explosives), Firearms/Toolmarks, Impression Evidence, and Biology.

The crime laboratory receives an average of 7000 requests to test evidence, which results in approximately 50,000 tests and 15,000 items tested annually. The laboratory utilizes forensic databases as essential crime fighting tools which have provided and continue to provide important investigative leads for law enforcement. Database “hits” are routinely processed in the Firearms and DNA sections. Annual monies are received through local and federal grants to upgrade instrumentation, validate new technologies, provide training for scientists, and increase efficiency and capacity within the sections.
