Grandparentage DNA Test
Grandparentage DNA testing will tell you whether a grandmother and grandfather are the biological relatives of their grandchild. This test is often done in the place of a paternity DNA test in cases when the biological father of a child is unavailable or deceased and thus, a paternity DNA test is not possible.

Using the DNA of alleged fathers parents we can tell you whether these individuals are genetically related to their grandchild/children and thus, whether the children tested are their father’s children.

We offer two types of grandparentage tests

  • Duo grandparentage DNA test: This is the ideal test as it allows us to reconstruct both grandparents genetic profiles and have a fuller insight of genetic inheritance patterns in relation to the child.
  • Single grandparentage test:  Grandparentage DNA testing can be done with a single grandparent albeit with less accuracy. In a single grandparents DNA test we strongly recommend addition of the mother’s sample.

Note that if the test involves alleged grandfather and male grandchild, we can confirm their biological relationship with a Y chromosome test.

You results will show the probability of a biological grandparentage which will be expressed as a percentage.

Cost and turnaround time

The grandparentage test is offered at $450 for grandmother, grandfather and grandchild. Your results will be sent by email in 3-5 business days, unless you specify otherwise.
