Minimizing contamination in products used to collect and analyse biological material for forensic purposes

Section Menu

The framework for the forensic standards development consists of four core standards that provide a comprehensive matrix and are applicable to the majority of forensic science disciplines. These can then be supported by the development of discipline specific forensic science standards, referencing the core standards for the more universal aspects of forensic science practice such as collection of forensic material, examination techniques, interpretation of analytical results and reporting findings.

The effectiveness of DNA profiling as an investigative and evidentiary tool is weakened by sample contamination. Contamination occurs when extraneous DNA is mixed with the DNA relevant to the case. This can occur at many points in the forensic process from the crime scene to the laboratory, and including the manufacture of consumables and products used by crime scene examiners or within the laboratory. A discipline specific Standard was identified for development early to address this issue.
