As a CODIS participating laboratory, CHI maintains and administers a local CODIS database.

CODIS is the acronym for the Combined DNA Index System, the FBI's program of support for criminal justice DNA databases, as well as the software used to run these databases. CODIS merges forensic science and computer technology into a tool for linking crimes and persons, and enables federal, state, and local CODIS participating laboratories to electronically exchange and compare DNA profiles.

CHI has current ownership of over half of the specimens residing in the national CODIS missing persons indices (relatives of missing persons and unidentified remains profiles), by which DNA associations help to identify missing and unidentified individuals from across the nation. CHI has also uploaded DNA profiles from forensic casework, including sexual assault, homicide, robbery, aggravated assault, burglary, theft, and other violent crime and property crime cases, leading to the generation of countless investigative leads for law enforcement agencies.

The DNA Identification Act of 1994 formalized the FBI's authority to establish a National DNA Index System (NDIS) for law enforcement purposes. The DNA Act specifies the categories of data that may be maintained in NDIS (convicted offenders, arrestees, legal, detainees, forensic casework evidence, unidentified human remains, missing persons, and relatives of missing persons), as well as requirements for participating laboratories relating to quality assurance, privacy, and expungement. Currently, DNA data generated through PCR Short Tandem Repeat (STR) technology, Y chromosome STR (Y STR) technology, and Mitochondrial DNA (mtDNA) technology are accepted in CODIS. Y STR and mtDNA data are only searched within the missing person-related indices.
