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.
