Initially drafted by OSAC’s Footwear & Tire Subcommittee and finalized by ASB’s Footwear and Tire Consensus Body, this document provides the best practice recommendations for personnel responsible for photographic documentation of footwear and tire impressions for future examinations. Deviations from this document may/may not preclude examination of captured images. The procedures included in this document may not cover all aspects of footwear and tire photography. This document is not intended as a substitute for training in the documentation and photography of footwear and tire track evidence.
• ANSI/ASB Standard 119, Standard for the Analytical Scope and Sensitivity of Forensic Toxicological Testing of Blood in Medicolegal Death Investigations, First Edition, 2021. Initially drafted by OSAC’s Forensic Toxicology Subcommittee and finalized by ASB’s Toxicology Consensus Body, this standard delineates the minimum requirements for target analytes and analytical sensitivity for the forensic toxicological testing of blood specimens collected in medicolegal death investigations. This standard does not cover the analysis of urine, tissues, or other specimens that are commonly analyzed in medicolegal death investigations.
• ANSI/ASB Standard 120, Standard for the Analytical Scope and Sensitivity of Forensic Toxicological Testing of Blood in Impaired Driving Investigations, First Edition, 2021. Initially drafted by OSAC’s Forensic Toxicology Subcommittee and finalized by ASB’s Toxicology Consensus Body, this standard delineates the minimum requirements for target analytes and analytical sensitivity for the forensic toxicological testing of blood specimens collected from drivers suspected of being impaired. This standard does not cover the analysis of breath, oral fluid, urine, or other specimen types collected in impaired driving investigations.
• ANSI/ASB Standard 131, Standard for Training in Forensic DNA Sequencing using Capillary Electrophoresis, First Edition, 2021. Initially drafted by OSAC’s Human Forensic Biology Subcommittee and finalized by ASB’s DNA Consensus Body, this standard provides the general requirements for a forensic DNA laboratory’s training program in forensic DNA sequencing using capillary electrophoresis. This standard applies to forensic human and wildlife mitochondrial DNA capillary electrophoresis sequencing, and wildlife nuclear DNA capillary electrophoresis sequencing.
