Sibling, Grandparent and Avuncular Legal DNA Testing
Our legal DNA tests determine if two or more people are related with statistical probability and specific documentation that is court admissible. We specialize in the following accredited legal DNA tests performed by our AABB accredited testing partner:
All DNA tests performed for use by a government agency, or in a court case require a specialized collection process, a legal chain of custody for the DNA samples, and testing in an AABB accredited laboratory using the authorized maximum number of DNA genetic markers.
Legal relationship DNA collections
Since 2018 AABB requirements for legal relationship DNA collections require that a legal DNA collection kit cannot be in the control of any person who is having the testing done at any point in the process. AABB testing protocols also state that whoever is performing the mouth swab collection must meet one of the following criteria: have performed DNA collections for at least one year; have received web-based training from the AABB for relationship collections; have been trained either in person or with web based training from a DNA testing laboratory. Licensed physcian’s may also be accepted as DNA collectors.
How will my DNA collection be handled?
We can arrange for the collection of your legal DNA test, or you can choose to have it sent to a physcian of your choosing. If those who need to be tested are in different locations, that is not a problem. We will apply either of these options for all those involved.
A legal relationship DNA test is not difficult to perform. Journey Genetic Testing can send a Legal DNA Collection Kit to an independant third party (such as your doctor’s office, a local lab or hospital of your choosing). It is not necessary for each person to test at the same time, and people in different locations can have a legal DNA test done at a location close to them, as long as all instructions are followed.
The entire process of a Chain of Custody (legal) DNA collection is described below.
-The sample collection process must be conducted by an unrelated person who does not have an interest in the outcome of the testing).
-The collector must verify the identity of those whom are testing by confirming legal identification (e.g. driver’s license, birth certificate, passport, etc.);
-The collector must obtain and submit picture identification of those testing;
-The witness must sign the completed chain-of-custody witness document provided in the kit as a witness to the collection;
-The witness must seal the DNA specimens in the container provided in the kit, sign the security seal, and mail the samples directly to the laboratory for testing.
Journey Genetic Testing will provide a legal collection kit to the closest collection center based on the zip code(s) of those being tested.
We will provide you the name and location of the collection center when the collection kit is mailed out. We cannot guarantee a collection center in every city, but we do work with a collection network of over 3,500 certified DNA collectors within the USA. Once the collection center has the kit, you will be notified of an appointment time.
