The importance of testing both Grandparents
By testing the DNA of both the grandfather and the grandmother, the reconstructed DNA is used to establish a DNA profile for the parent of the child in question. Total DNA Services then compares the child sample to the reconstructed DNA sample provided by the grandparents, to either confirm or rule out if the parent is biological to them.
There are two options offered when ordering this test:
Grandparent DNA Test
This is used to verify the biological relationship (if there is one) between a child and their grandparents.
Duo Grandparent DNA Test
Comparing both the grandfather and grandmother’s DNA to the child’s. A sample from the mother is not required for this test.
Male only DNA Tests
If the participants providing samples are only male, a Y Chromosome Test is advised. This is the best way of confirming a paternal bloodline, as males from the same paternal line will have a copy of the same Y chromosome. If results indicate that two (or more) males share the same Y chromosome, then they will also share a paternal relative.
