If in doubt, criminal justice providers are urged to contact the lab for advice related to problems confronting their investigation. (Find your laboratory here) State Crime Laboratories are open Monday through Friday, 7:45 am to 4:30 pm, except holidays.

Evidence Submission Information for Criminal Defense

Upon court order, the services of the State Crime Laboratory are available at no cost to a defendant in a felony action. (Find your laboratory here) Results are confidential to the defense.


Often, the items to be examined are in the custody of a police agency. While the agency may be directed to act as courier to deliver and retrieve items after analysis, results will not be discussed with them.


State Crime Laboratory services are not available for civil cases.
