Laboratory Requests/Evidence Submissions

As a result of compliance with accreditation standards, there are certain requirements of communication and policies regarding case acceptance that must be upheld by the DPS Crime Laboratory Service.

Physical Evidence Handbook (PDF) outlines specific parameters/limitations regarding the submission of evidence and our statement of services provided by a DPS Crime Laboratory.

Section 1 contains General Information, including Statement of Services (PEH-01-02), Scope of Testing (PEH-01-03; Laboratory Services and Laboratory Contact Information), and Instructions for the completion of the Laboratory Submission Form (PEH-01-05).

Sections 2 and 3 deal with Evidence Collection and special evidence considerations.

ATTENTION – In an effort to provide more efficient and effective service for Drug, DNA, GSR Primer Residue, and computer forensic testing requests, the DPS Crime Laboratory Service has implemented the following case acceptance policies:
  • Drug Evidence Submission and Acceptance Policy (PEH-02-02)
  • DNA Case Acceptance Policy (PEH-02-04A)
  • DME Case Acceptance Policy (PEH-02-08B)
  • GSR Case Acceptance Policy (PEH-02-05A)
