Collection of Samples for DNA Analysis.
Effective sampling of biological material is critical to the ability to acquire DNA profiles of probative value. The main methods of collection are swabbing, tapelifting, or direct excision. This chapter describes the key aspects to consider when applying these methods, in addition to suggested procedures for swabbing and tapelifting. Important issues to be considered, such as exhibit triaging, pre-examination preparation, contamination risk reduction, sample localization, sample identification, and sample prioritization as well as aspects of record keeping, packaging, and storage, are also raised.
