Frequently Asked Questions


What is TrueAllele® technology?

TrueAllele computing was invented by Dr. Mark Perlin. It accurately, objectively and rapidly analyzes DNA evidence from crime scenes. The method produces reliable answers on DNA mixtures with any number of contributors.

How does TrueAllele technology work?

After a lab develops DNA data from crime scene evidence, the data files are uploaded into the TrueAllele computer. The computer separates the DNA mixture into individual genotypes. Then the computer makes comparisons between the evidence and known references (people). The result of the comparison is a match statistic.

Can laboratories use TrueAllele technology?

Government laboratories can purchase their own TrueAllele systems. See Products.

DNA evidence and cases

The lab said the DNA was “inconclusive” or that there was "insufficient genetic information." Can TrueAllele technology help?

Yes. The computer has found information when other methods did not. TrueAllele computing resolves items with multiple contributors, partial profile and degraded DNA. See Trials for examples.

I don’t have a suspect. Can TrueAllele technology help?

Yes. TrueAllele computing infers genotypes (genetic types, or DNA profiles) from the evidence. The inferred profile can be searched in a database, like CODIS, or used to provide probable cause.

The suspect(s) and victim are related. Can TrueAllele technology help?

Yes. TrueAllele computing has unmixed father-daughter, brother-brother and other family DNA data into individual profiles. Read more in Trials and Newsroom.

Does Cybergenetics only work for prosecutors and investigators?

No. Cybergenetics analyzes case data for defenders and innocence groups, as well as prosecutors and investigators. Also, Cybergenetics partners with academics, advocates and labs.

My client claims not to be present on the evidence. Can TrueAllele technology look?

TrueAllele computing is neutral. If a person is connected to the evidence, the computer calculates inclusionary statistics. If a person is not connected to the evidence, it calculates exclusionary statistics.

Are TrueAllele results admissible in court?

Yes. Courts across the globe have admitted the TrueAllele method. See Admissibility and Trials.

Submitting a case

How do I send a case for a free TrueAllele screening?

Contact Cybergenetics. For detailed instructions, visit Sending Data.

Are the physical evidence items needed for TrueAllele processing?

No. The computer uses the DNA data, which crime labs develop from biological evidence items. Only the electronic data file is needed for TrueAllele processing.

How long does processing take?

TrueAllele system can process hundreds of evidence items in days. Cybergenetics typically delivers results from a free TrueAllele screening within a few weeks.

What does my match statistic mean?

A big match number, like one million, is statistical support that the person contributed their DNA to the given item. A small number, like one-in-a-million, is statistical support that the person did not contribute DNA to the given item.
