Grandparentage DNA Test

Grandparentage DNA testing will establish the probability of the tested grandparents being the biological grandparents of their grandchild child.

Grandparents might be required to do such a DNA test if their grandchild’s alleged father is dead or unavailable for a DNA test and there are doubts relating to the issue of paternity.

homeDNAdirect Australia offer two basic types of grandparentage tests. The first, the one we always recommend, would include the DNA samples of the grandchild’s paternal grandmother and grandfather as well as DNA samples of the grandchild. This test is ideal in that it provides our scientists with the possibility of having a more complete genetic profile for comparison and analysis purposes. We also do many grandparentage tests with only a single grandparent which can also provide meaningful results.

As with any order Relationship DNA Test, adding the sample of the mother is strongly recommended if available to help strengthen the final result.

In cases necessitating grandfather-grandson testing, and therefore the participants are male, you will need to do a Y-Chromosome test. 

The grandparentage test for one grandparent and their grandchild is priced at AUD $589. You will have your results in 5-7 working days. You can order your test here.
