Context
These UK Forensic Science Regulator set the requirement for the forensic medical examination rooms within a Sexual Assault Referral Centres (SARC) to have an air flow replacement of >20 whole room replacement per hour to reduce the risk of DNA contamination. However, there is no published research on airflow replacement systems and their effect to the risk of DNA contamination. This study involved investigating the risk of varied airflows within SARC forensic medical examination rooms with the use of the Coriolis Compact air sampler to vacuum DNA from the air which was subsequently analysed for DNA contamination.
