Forensic Grandparent DNA Test

Forensic Grandparent DNA Testing

Helping You Achieve Peace of Mind

Proving Family Relationships When a Parent Isn’t Available

When a parent is deceased, missing, or unwilling to participate in testing, a Forensic Grandparent DNA Test can help establish a biological link between a grandchild and the alleged grandparents. Using non-standard samples, like hair, toothbrushes, razors, or personal items, we provide accurate, discreet results with no cheek swab required.

What Is a Forensic Grandparent DNA Test?

A Forensic Grandparent DNA Test determines whether a child is biologically related to one or both grandparents when the parent (usually the alleged father) is not available for testing. This test works by comparing the child’s DNA with the grandparents’ to identify shared genetic markers.

Why You Might Need This Test

  • The alleged father is deceased or unreachable

  • You need evidence for inheritance matters

  • You want to confirm a biological connection through the paternal or maternal line

  • Only personal items or discreet samples are available

  • The child or parent is not willing or able to test

Common types of forensic samples

Acceptable Forensic Samples

When grandparents can’t provide a cheek swab, or have passed away, we can extract DNA from forensic samples like:

  • Toothbrushes

  • Hair with roots

  • Razors

  • Used clothing

  • Cigarette butts

  • Chewing gum

  • Dried blood stains

Note: The success of DNA extraction depends on the quality and condition of the sample. Please contact us to discuss the viability of your specific sample.

*Please note Special Samples do not include: Teeth, Bones, Bone Marrow, Organs or Muscle Tissue, Feces, Paraffin Embedded Tissue, or FFPE. *

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).

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.
