Rapid DNA technology will provide law enforcement booking personnel the ability to process and query reference samples obtained from qualifying arrestees against unsolved crimes of special concern in real-time, potentially enhancing the speed of an investigation. The technology could also be utilized within the laboratory setting to expedite the processing of reference samples submitted with a case. Validation studies have found that when used with reference samples, the ANDE 6C Rapid DNA technology generates successful profiles that are concordant to orthogonal system generated data ∼85 % of the time. The success rate, however, appears to be contingent on the use of the ANDE swab. During this study a comparison between ANDE and conventional cotton swab results was performed to establish if there was a difference in success rate between the two substrates. The results demonstrate a substantial decrease in expert system passing profiles when conventional swabs were used. For those instances, a modified Rapid DNA protocol could be developed to aid in the recovery of the data.
