| Abstract: | As the sensitivity and discriminative power of DNA technology progressively improves, the ability to utilise trace DNA as evidence in forensic casework similarly increases. Along with increased sensitivity comes the prospect of detecting contaminating DNA, complicating the interpretation of profiles. This study aimed to provide data into the occurrence and level of DNA potentially transferred between high risk vectors (scissors, forceps, gloves) and exhibits during the examination process in both light and heavy contamination/contact scenarios. DNA transfer was observed for all vectors in both transfer situations, with heavy conditions transferring more than light. Profiles with sufficient alleles to identify the origin were observed for each vector in both heavy and light scenarios, excluding forceps, where only a small number of alleles were transferred under light conditions, |
