    •  Streamlined and Time Saving •  Simple User Interface allowing users to define their own standard curve values

    for all targets.

    •  Analyst time saving as well as assist in workflow decision making. •  Efficiency and Cost Savings

    •  The virtual standard curve feature allows for samples to be run in the place of standards, increasing throughput

    •  Flexibility •  Adaptable analysis settings allowing for permutations of running and analyzing

    with traditional or virtual standard curves.

    •  Accuracy •  Mitigates concerns of variability introduced due to operators on

    standard curve.

    Virtual Standard Curve Benefits

  • 11

    Accurate results in less time for your most challenging samples.

    •  Greater correlation with downstream results when used in conjunction with

    latest generation STR Kits

    •  Increased robustness of reactions help deliver better correlation of results to the latest generation STR kits

    •  Evaluate sample quality (degradation and inhibition) and quantity in a single reaction.

    •  Improved IPC helps deliver results that correlate to dropout in the STR kit reaction •  Accurate negative results and quality index deliver confidence in downstream processing

    Quantifiler Trio Kit: A Sample Assessment Solution

    Quantifiler Trio Results Indicates Processing Options*

    Male quantity (Y target) = undetected Insufficient male DNA

    Stop processing or prioritize other case samples

    High Male:Female ratio Unlikely to obtain informative male autosomal STR profile Perform Y-STR analysis

    IPC CT shift Significant PCR inhibitors present Dilute and/or re-purify sample

    Degradation Index (DI) > 1 or blank DNA degradation likely

    1)   Concentrate sample 2)   Increase DNA target and/or sample

    input volume for STR rxn 3)   Consider NGS

    •  Enables rapid sample assessment for more informed casework lab processing decisions

    * These are general guidelines that may not apply to all samples depending on the inhibitors present, the varying quantity of contributor DNA in mixed samples and the STR kit used. Perform validation studies to determine interpretation guidelines and procedures for your laboratory.

    Why are Sexual Assault Samples Challenging?

    Time-consuming

    •  Among the most difficult samples encountered by forensic labs

    •  At least 4-6 hours to review evidence in a single SAK

    •  A high percentage of cases for many laboratories

    Sample Quality

    •  Small quantity of male DNA with relatively high quantity of female DNA

    •  30-50% of SAKs yield no male DNA1

    •  PCR inhibitors or DNA degradation

    Labor-intensive

    •  Microscopic sperm search

    •  Serological assay Interpretation issues

    •  Differential extraction

    Y-Screen for swabs Uses the Quantifiler™ Trio kit as an upfront DNA confirmatory swab screening method to detect the quality and presence/absence of amplifiable male DNA

    •  Streamlined solution that can reduce number of backlogged samples and better manage incoming cases

    •  Empowers analysts with qualitative data to confidently identify samples with amplifiable male DNA

    •  Quickly eliminates labor-intensive differential extractions of samples where no male DNA is present

    Y-screen Protocol Options

    Reduce Backlogged Samples

    Streamline Use of Differential Extraction

    Empower Confident Decision Making

    •  Screen swab evidence in SAKs quickly for the presence/ absence of male DNA

    •  If male DNA is present, process swab for STR

    •  If no male DNA is present, write report, no further processing

    •  Eliminate differential extractions for negative Y-Screen and presumptive testing samples

    •  Process only the main

    SAK swabs with differential extraction, and use Y-Screen for other swab evidence

    •  Add a DNA confirmatory test to complement presumptive screening tests

    •  Better inform analyst decisions on the presence/absence of male DNA in sexual assault kit swab samples

    Sexual assault kit DNA screening prior to standard sexual assault sample processing workflow

  • 19

    •  “Direct to DNA” for the process of foregoing traditional serology

    •  “Although the detection and characterization of body fluids in a forensic laboratory has not changed considerably over time, DNA testing has dramatically increased in sensitivity.”

    •  “Processing the swabs from a SAK for DNA first allows for potential reduction in false negative serology results of swabs that are not moved on for DNA analysis because they fell below the serological test’s limit of detection.”

    Y-Screen Test Site Commentary

    “Predicted downstream STR results better than traditional screening

    assays”

    “It tells you for sure what not

    to move through”

    “Protocol was quick and easy to

    use – very straightforward”

    “There weren’t any samples that failed to give a positive Y-Screen result that went on to give a

    usable profile”

    “Could eliminate 1/3 to 1/4 of our

    samples upfront so it

    could save us a great

    amount of time”
