Introduction: DNA as a forensic tool has been used to link suspects to crime scene evidence for
the past three decades. The latest breakthrough in DNA forensics, Rapid DNA testing, promises
to be a disruptive new technology that will dramatically improve the effectiveness of criminal
justice systems worldwide. By reducing the turnaround time of suspect samples from days, weeks
or even months to 90 minutes, law enforcement officials, forensic scientists and prosecutors can
apply this tool to a wider variety of crimes. They are preparing for this amazing breakthrough by
validating the technology, running pilot studies and examining workflows to make sure they can
quickly take full advantage of Rapid DNA. This paper describes the current state of DNA as a
forensics tool, the emerging technology of Rapid DNA, and some early uses of the first
commercial implementation of Rapid DNA – the IntegenX RapidHIT™ 200 Human
Identification System.
