New publication - The reliability and reporting of DNA match strength for uncertain genotype evidence.

I don’t have a suspect yet. Is TrueAllele® screening still helpful?

Short answer

Yes. Even without a suspect, TrueAllele Casework services can provide useful investigative information. The same lab DNA data can still be screened to see whether the evidence is informative and whether it may support next investigative steps.

What to do next

  1. Identify the most probative evidence items first.
  2. Request the required electronic DNA data files (.fsa or .hid).
  3. Submit a Free TrueAllele Screening inquiry.
  4. Use the result to decide whether the evidence helps further the investigation.

What to send

  • Please do not send biological evidence. The screening uses the lab’s autosomal STR electronic DNA data files (.fsa or .hid).

Please submit:

  • For key evidence items, the lab’s electronic data (.fsa or .hid)
  • For reference profiles (victim/elimination/POI), either allele lists or electronic data files
  • Allelic ladder files for any electronic data
  • Lab reports or other case documents
  • Item ID list (which swabs/items the files belong to)
  • A case submission form with case specific information and questions (e.g., compare to POI, interpret the inconclusive mixture, compare items, etc.)

For more information on what to request from the lab, see the Sending Cases for TrueAllele Processing page.

We don’t retest physical evidence items. We interpret the electronic DNA data a lab already generated.
