Grandparentage DNA testing can be used when grandparents need to confirm the biological relationship to their grandchild. This test will show the statistical probability that the grandparents are genetically related to their grandchild.

Requirements for the grandparentage DNA test

We suggest a grandparents test when clients need to establish the paternity of a child through the child’s paternal grandparents. We recommended testing both grandparents if available as this will help obtain more conclusive results. As in all relationship testing, the sample of a common parent (normally the mother) is always recommended. The price of the grandparents test will change according to the number of people being tested.

Options for grandparentage analysis

  1. DNA analysis of single grandparent: this test requires DNA samples from just ONE of the grandparents. We do not offer single grandparents testing and suggest you contact us to discuss alternative tests in such cases.
  2. DNA analysis of both grandparents: We can only offer grandparent testing if we have samples from both grandparents. The mother’s sample should also be included if available.

In both types of tests the DNA profiles analyzed are compared with that of the grandchild to establish a biological relationsip. The mother’s samples are included to quickly eliminate her share of the DNA in the heredity process, which in turn leaves just the paternal half to test. This will help provide a stronger result.

Test results are intended to provide a statistical likelihood that gives evidence to support the tested relationship in question. Results are normally sent by email within 7-10 working days from when we receive the samples at the laboratory.

Note: We can only guarantee standard result turnaround time when testing takes place solely using oral swab samples. Using a discreet sample for your test may lead to an increase in turnaround time.

The cost of grandparentage test starts from as little as From $949 .

Grandfather and grandchild

If testing is between grandfather and grandchild, and involves only male relatives we suggest doing a Y chromosome test. This test is highly accurate and will confirm a shared paternal line between tested parties. Click here for more information.
