Grandparentage DNA Test

A grandparentage DNA test seeks to determine whether a true biological relationship exists between grandparents and their grandchild. This type of test is often used as an alternative to a DNA paternity test. Testing the alleged father’s parents will indicate whether the tested child is his biological child; if he is not the child’s paternal father than both grandparents will result in exclusion when their DNA is compared to their grandchild’s.

3 types of grandparentage DNA tests are available:

• Duo Grandparentage test – this test involves providing DNA samples of both grandfather and grandmother from the father’s side along with the grandchild. This test is strongly recommended because it provides results which are more reliable.

• Single Grandparentage test – This test involves testing just one grandparent. 

• Y-chromosome testing – done when the test is carried out between grandfather and male grandchild only

Whichever grandparent test you opt for, sending in the mother’s sample will be of great help to improve the results. Our analysts can use the mother’s DNA profile to determine what genes she has passed on to her child and provide a stronger result for the overall test. If the mother is unavailable, we can still go ahead with the testing.

The Grandparentage DNA test is priced from €385. Results will be emailed to you in 5-7 working days. You can also specially arrange with us to receive them by post. Order Here your test.
