Laurin N, Boulianne H, Frégeau C. Comparative analysis of two Rapid DNA technologies for the processing of blood and saliva-based samples. Forensic Sci Int Genet 2023; 67:102928. [PMID: 37573630 DOI: 10.1016/j.fsigen.2023.102928] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2023] [Revised: 07/30/2023] [Accepted: 08/07/2023] [Indexed: 08/15/2023]
Abstract
Rapid DNA technologies recently gained significant momentum as a means to generate DNA profiles faster than with standard laboratory workflows. Initially developed for the analysis of buccal reference samples, applications are being considered for other types of forensic samples. In this study, an identical set of 150 blood and saliva-based samples was processed using two different Rapid DNA technologies, the Applied BioSystems™ RapidHIT™ ID System using the RapidINTEL™ sample cartridge and the ANDE™ 6C Rapid DNA Analysis™ System using the I-Chip. A subset of samples were subjected to alternative collection methods or sample pre-treatments to determine the optimal strategy for each instrument. An equivalent sample set was also processed using a conventional DNA analysis workflow. The sensitivity range of the two Rapid DNA technologies was comparable based on blood and saliva dilution series, with both technologies able to generate full profiles from samples typically yielding 5-10 ng of DNA when processed using conventional DNA analysis. The brand of cotton swabs used for Rapid DNA analysis had an impact on the results for both systems. Differences were observed in success rate between the two systems when processing blood (on fabrics, FTA paper or hard surfaces) and saliva-based samples (drink containers, FTA paper, chewing gum, cigarette butt filter paper) and depended on the sample type. Importantly, deviating from the manufacturer's instructions for sample collection and pre-treatment was more detrimental to the ANDE 6C results. The quality of DNA profiles, as assessed using heterozygote peak height ratios, interloci balance and artifact presence, confirmed the results to be reliable and acceptable for single source samples. Profiling results were obtained when samples were reprocessed using the same Rapid DNA technology or conventional DNA analysis. Secondary analysis using a substitute software (GeneMapper ID-X v1.5) to recover additional genetic information was shown to be feasible. Finally, a comparison between the Applied Biosystems™ RapidHIT™ ID System Software v1.3.1 and v1.3.2 was also performed. Findings of this study could assist those interested in using Rapid DNA technology for blood or saliva-based samples, in various settings and for different applications.

Abstract
An automated system of DNA profile processing (termed a 'lights-out' workflow) was trialled for no-suspect cases over a three-month period at Forensic Science SA (FSSA). The lights-out workflow utilised automated DNA profile reading using the neural network reading feature in FaSTR™ DNA with no analytical threshold. The profile information from FaSTR™ DNA was then processed in STRmix™ using a top-down analysis and automatically compared to a de-identified South Australian searchable DNA database. Computer scripts were used to generate link reports and upload reports and these were compared to the links and uploads that were obtained for the cases during their standard processing within the laboratory. The results of the lights-out workflow was an increase in both uploads and links compared to the standard workflow, with minimal adventitious links or erroneous uploads. Overall, the proof-of-concept study shows the potential for using automated DNA profile reading and top-down analysis to improve workflow efficiency in a no-suspect workflow.

Turiello R, Nouwairi RL, Landers JP. Taking the microfluidic approach to nucleic acid analysis in forensics: Review and perspectives. Forensic Sci Int Genet 2023; 63:102824. [PMID: 36592574 DOI: 10.1016/j.fsigen.2022.102824] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2022] [Revised: 12/02/2022] [Accepted: 12/19/2022] [Indexed: 12/24/2022]
Abstract
Forensic laboratories are universally acknowledged as being overburdened, underfunded, and in need of improved analytical methods to expedite investigations, decrease the costs associated with nucleic acid (NA) analysis, and perform human identification (HID) at the point of need (e.g., crime scene, booking station, etc.). In response, numerous research and development (R&D) efforts have resulted in microfluidic tools that automate portions of the forensic genetic workflow, including DNA extraction, amplification, and short tandem repeat (STR) typing. By the early 2000 s, reports from the National Institute of Justice (NIJ) anticipated that microfluidic 'swab-in-profile-out' systems would be available for use at the crime scene by 2015 and the FBI's 2010 'Rapid DNA' Initiative, approved by Congress in 2017, directed this effort by guiding the development and implementation of maturing systems. At present, few fully-automated microfluidic DNA technologies are commercially available for forensic HID and their adoption by agencies interested in identification has been limited. In practice, the integration of complex laboratory processes to produce one autonomous unit, along with the highly variable nature of forensic input samples, resulted in systems that are more expensive per sample and not comparable to gold-standard identification methods in terms of sensitivity, reproducibility, and multiplex capability. This Review and Perspective provides insight into the contributing factors to this outcome; namely, we focus on the complications associated with the tremendous undertaking that is developing a sample-in-answer-out platform for HID. For context, we also describe the intricate forensic landscape that contributes to a nuanced marketplace, not easily distilled down to cases of simple supply and demand. Moving forward and considering the trade-offs associated with developing methods to compete, sometimes directly, with conventional ones, we recommend a focus shift for microfluidics developers toward the creation of innovative solutions for emerging applications in the field to increase the bandwidth of the forensic investigative toolkit. Likewise, we urge case working personnel to reframe how they conceptualize the currently available Rapid DNA tools; rather than comparing these microfluidic methods to gold-standard procedures, take advantage of their rapid and integrated modes for those situations requiring expedited identifications in an informed manner.

Abstract
This systematic review describes and discusses three commercially available integrated systems for forensic DNA analysis, i.e., ParaDNA, RapidHIT, and ANDE. A variety of aspects, such as performance, time-to-result, ease-of-use, portability, and costs (per analysis run) of these three (modified) rapid DNA analysis systems, are considered. Despite their advantages and developmental progress, major steps still have to be made before rapid systems can be broadly applied at crime scenes for full DNA profiling. Aspects in particular that need (further) improvement are portability, performance, the possibility to analyze a (wider) variety of (complex) forensic samples, and (cartridge) costs. Moreover, steps forward regarding ease-of-use and time-to-result will benefit the broader use of commercial rapid DNA systems. In fact, it would be a profit if rapid DNA systems could be used for full DNA profile generation as well as indicative analyses that can give direction to forensic investigators which will speed up investigations.

Abstract
Rapid DNA technology is being utilized for reference profiles worldwide. There is also strong data in the literature to support its use for high-template DNA sources, the same is not true for low-template sources, such as touch DNA; this is a requirement before wider implementation to forensic casework is considered. We report on the Rapid HIT Intel cartridge's ability to facilitate successful amplification of touch DNA to obtain profiles from template deposited on items commonly encountered in forensic casework. Eight items were touched in ten replicates- two were tapelifted, three swabbed, and three directly inserted. Significance was observed in the alleles amplified and RFU with respect to sample type. Three samples performed well: cable tie, fabric, and matchstick. As two of these were directly inserted, this should be considered for any sample small enough. Placement of highly absorbent substrates into the cartridge is not advised as it can cause a lysate-pull error. Heterozygote loci often presented as homozygous (32%-78% loci per profile); this was influenced by substrate type and profile RFU. Loci with larger masses exhibited higher false homozygosity also. Comparison of the donor's profile analyzed was performed against previous datasets analyzing touch DNA through standard workflow, including manual DNA extraction, PCR, and CE separation. These data show that for all substrates, except for a fabric swatch, standard processing is preferential to Rapid HIT analysis. In its current form, rapid DNA technology is not fit for the routine analysis of touch DNA samples in forensic casework.

Abstract
Forensic investigation is important to analyze evidence and facilitate the search for key individuals, such as suspects and victims in a criminal case. The forensic use of genomic DNA has increased with the development of DNA sequencing technology, thereby enabling additional analysis during criminal investigations when additional legal evidence is required. In this study, we used next-generation sequencing to facilitate the generation of complementary data in order to analyze human evidence obtained through short tandem repeat (STR) analysis. We examined the applicability and potential of analyzing microbial genome communities. Microbiological supplementation information was confirmed for two of four failed STR samples. Additionally, the accuracy of the gargle sample was confirmed to be as high as 100% and was highly likely to be classified as a body fluid sample. Our experimental method confirmed that anthropological and microbiological evidence can be obtained by performing two experiments with one extraction. We discuss the advantages and disadvantages of using these techniques, explore prospects in the forensic field, and highlight suggestions for future research.

Abstract
Rapid DNA platforms are fully automated systems capable of processing DNA from biological samples and interpreting the results in approximately 90 minutes with minimal human intervention. With a greater reliance on the system than on the analyst, validation data are especially needed to define the performance and limitations of commercially available Rapid DNA systems. Thus, validation studies of a Rapid DNA workflow consisting of the Applied Biosystems RapidHIT ID Instrument and RapidLINK software with a focus on the ACE GlobalFiler Express Sample Cartridge and reference buccal swabs were performed in accordance with Scientific Working Group on DNA Analysis Methods Validation Guidelines. These validation studies included assessments of sensitivity, contamination, concordance, reproducibility and repeatability, stability, inhibition, mixtures, sample reprocessing, precision, and first-pass success rate. Overall, the current Applied Biosystems RapidHIT ID Instrument with the ACE GlobalFiler Express sample cartridge was found to be a reliable tool for generation of STR profiles from reference-type buccal swabs.

Abstract
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.

Abstract
Rapid DNA analysis is an ultrafast and fully automated DNA-typing system, which can produce interpretable genetic profiles from biological samples within 90 minutes. This "swab in-profile out" method comprises DNA extraction, amplification by PCR multiplex, separation and detection of DNA fragments by capillary electrophoresis. The aim of study was the validation of the Accelerated Nuclear DNA Equipment (ANDE) 6C system as a typing method for reference samples according to the ISO/IEC 17025 standard. Here, we report the evaluation of the validity and reproducibility of results by the comparison of the genetic profiles generated by the ANDE 6C System with those generated by standard technologies. A quantity of 104 buccal swabs were analyzed both through the ANDE 6C technology and the traditional method (DNA extraction and quantification, amplification and separation by capillary electrophoresis). Positive typing was observed in 97% of cases for ANDE 6C technology with only three buccal swabs failing to reveal interpretable signals. Concordance was determined by comparing the allele calls generated by ANDE 6C and conventional technology. Comparison of 2800 genotypes revealed a concordance rate of 99.96%. These results met the ISO/IEC 17025 requirements, enabling us to receive the accreditation for this method. Finally, rapid technology has certainly reached a level of reliability which has made its use in laboratories of forensic genetics a reality.
