To perform DNA testing on crime scene evidence, all of RI’s convicted felons and violent crime arrestees and upload these profiles into the FBI’s DNA database, the Combined DNA Index System (CODIS) to assist in criminal investigations.

What we do

  • Extract and generate DNA profiles from evidence samples and database samples using the current FBI core loci.
  • Compare evidentiary DNA profiles to reference samples taken from a victim or suspect.
  • Upload eligible case profiles, convicted felons, and arrestees, to CODIS and compare any potential matches.
  • Notify law enforcement of eligible matches to aid their investigation, both in RI and other states.


  • First laboratory in New England to successfully gain ISO 17025: 2005 national accreditation to the ISO/IEC 17025:2005 standards by the ANSI-ASQ National Accreditation Board (ANAB). This accreditation has been maintained for the last ten years.
  • Maintains a relatively large CODIS database when compared to other states with similar populations.
  • Data compiled from the DNA/CODIS program since inception: number of RI convicted felons in national CODIS DNA database: 24,299 ; number of RI violent crime arrestees in national CODIS DNA database: 452; number of RI investigations aided: 408. The National DNA Index (NDIS) contains over 13,202,969 convicted offender DNA profiles, 2,984,137 arrestee profiles, and 830,184 forensic (crime scene) profiles as of January 2018. As of that date, CODIS has produced over 406,211 hits (database matches) assisting 390,584 investigations. (Source: fbi.gov)
