DNA transfer in packaging: attention required

Items from crime scenes are frequently packaged and transported to laboratories for forensic examination. The packaging primarily maintains the integrity of forensic evidence associated with the item by protecting it from contamination and environmental impacts, plus limiting and recording access. There is diversity in the types of packaging used. We are aware that DNA-containing material may transfer from an item to the internal side of packaging and/or from one area of an item to another area, potentially limiting generation of good quality DNA profiles and/or affecting their interpretation.
