Additionally, this manual contains evidence submission acceptance criteria for items in need of forensic examination. The recommendations and the criteria help to ensure the integrity of the evidence and best analytical results. Every attempt has been made to make this handbook as current and up-to-date as possible; however, it should be noted that the field of forensic science is changing at a rapid rate. New techniques and procedures are constantly being developed, providing new capabilities or refinements to existing capabilities. Consequently, techniques, procedures and capabilities contained herein may change in the future. All agencies are encouraged to keep in regular contact with their local laboratory to keep abreast of any such changes.
