CTE Resource Center - Verso

Virginia’s CTE Resource Center

Demonstrate the storage procedures for DNA testing evidence.

Definition

Demonstration should include
  • separating and excluding any other biological evidence from DNA test evidence
  • preserving DNA material
  • following standard operating procedures for forensic laboratories.

Process/Skill Questions

  • What are the typical standard operating procedures for DNA evidence in forensic laboratories?
  • What steps are involved in storing and protecting DNA test evidence?
  • What would happen if DNA preservation methods were not followed?
