Laboratory Services (DNA and Toxicology)
DNA Services
The DNA Services section of the CBI advances justice through accurate and timely DNA analysis. The DNA Database stores genetic profiles collected under Colorado law to help solve crimes through CODIS, while individuals meeting specific legal criteria may request DNA Database Expungement for removal of their profiles. CBI is also dedicated to Eliminating the Backlog of DNA cases, particularly sexual assault kits, and ensuring all Sexual Assault Evidence Testing complies with state laws and victim consent requirements.
Toxicology Services
The Colorado Bureau of Investigation’s (CBI) Toxicology Services support DUI/DUID investigations, drug-facilitated crimes, and medicolegal death cases through precise Toxicology Testing conducted at no cost to law enforcement and coroners. With accredited Laboratory Locations in Denver, Grand Junction, and Pueblo, CBI ensures reliable results statewide. The Toxicology Dashboard provides secure access to case updates, while Blood Collection Kits simplify evidence submission. CBI toxicologists also offer Reports, Monographs, and Testimony to help interpret toxicology findings and their effects on human performance.
