Description
ParaDNA indicates whether samples collected at the crime scene contain human DNA and which of these are most likely to deliver investigative leads. It only takes 75 minutes to screen up to four samples and acquire this vital advance knowledge using fluorescent HyBeacons technology. The results indicate whether human DNA is present in sufficient quantity to generate a conventional STR profile upon submission to the laboratory. In addition, the sex of the sample donor is determined. ParaDNA does not supplant existing STR analysis, but augments the process and could save significant time and cost by effectively directing the investigative process. Using an innovative sample collector, minimal training is required to enable investigators to collect, assemble and analyze DNA. This poster presents the validation data that indicate the potential utility of the system in the United States, by screening several touch and saliva mock evidence samples.
