What is DNA and Genetic Testing

What is DNA and genetic testing?

DNA profiling used as a unique identifier was discovered in the 1980s. However, the genetic testing as we know it today was not developed until a decade later. 

The premise of DNA and genetic testing is centered on the fact that (other than identical twins) each person’s DNA is completely unique. 

This means that DNA can be used as human identification because of the unique STR loci that exist on autosomes and sex chromosomes within human DNA.

These chromosomes and STR loci can also be analyzed for forensic use and in legal proceedings. 

DNA as a unique identifier

Our DNA is constant and can’t be changed – unlike physical appearance which may change over time. A genetic identity can be used as a permanent identifier for every single individual on the planet.

Half of this unique set of information is passed down between parents and their children.  Thus enabling DNA to be used as a unique and reliable form of identification for paternity, siblings, and related parties.

What is AABB Accreditation?

Why does accreditation matter in DNA and genetic testing?

Firstly, what does AAbb accreditation even mean?

This certification is given to a very select few DNA laboratories that have undergone a highly intensive and rigorous inspection of their testing facilities and techniques to ensure all tests are done accurately and thoroughly with attention to detail.  It is an accreditation bestowed by the AABB (formerly the American Association of Blood Banks) and all laboratories with the accreditation are subject to proficiency tests and bi-annual re-inspections. Standards for the AABB accreditation can be found here.

Why does AABB matter to a DNA test?

Holding an AABB accreditation means a laboratory is on par with the best in the world and holds itself to the highest of measures within the DNA testing community.  An AABB accredited lab exceeds the industry standards in technique, accuracy, and modern scientific processes.

Additionally facilities with the AABB accreditation are the only DNA testing laboratories acknowledged by the U.S. Government to perform legal court admissible DNA tests, as well as provide services for the U.S. Department of Homeland Security and the U.S. Citizenship and Immigration Services (USCIS).
 

What other DNA Lab certifications are there?

If a laboratories meets AABB standards they are usually also certified to International Organization for Standardization (ISO) standards for technical competence, calibration, and lab testing. A laboratory compliant with ISO 17025:2005 and ISO 9001:2008 standards should incorporate the most advanced technical and quality management systems into all DNA, forensic, and genetic testing.

In addition a DNA and genetic testing laboratory may also hold accreditation or certification from national and international bodies such as:

DNA companies and their laboratories are governed by many standards, accreditation’s, and certifications. The most important of which is AABB and ISO. If your DNA test is important to you and you want the results to be as accurate as they can be, whether an informational Paternity DNA Test for private use or a legal Sibling DNA Test to be used in a legal matter, make sure the company that handles your DNA test offers AABB accredited and ISO certified results via an accredited laboratory.

WHAT KIND OF SAMPLES DO I NEED TO PROVIDE?

We primarily use simple oral buccal swabs (cheek cell collection) to collect samples for our quick easy home and legal DNA tests.

Validity Genetics can test from a variety of other types of samples. However, in these cases an extra fee may apply as well as a possible longer turnaround time for sample processing.

How fast can I get my results?

Validity Genetics offers a quick turnaround time of only two business days once received at the lab for all of our standard buccal swab DNA collection tests. We also have rush options available if needed (may not available on some special sample types such as Infidelity Testing).

How accurate are the tests?

Our procedures test for 22 genetic markers and the gender identification marker amelogenin. This ensures you receive 99.99% accurate test results.

A general principle for DNA testing is that the more genetic information available, the greater the precision of the test.

All of Validity Genetics' genetic testing services follow strict and validated procedures for processing samples to guarantee the utmost care of your samples.
