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 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.
