Grandparentage DNA Tests
At “dadchecksilver” we conduct scientific personal information grandparent DNA tests to determine if two or more individuals are related as paternal grandmother/grandfather and grandchild.
A grandparent DNA test may be performed instead of a paternity test when the alleged father is deceased, unavailable or unwilling to take part but the alleged father’s biological parent(s) are available.
How accurate are grandparent DNA tests?
Every one of us is unique. This uniqueness comes from our genetic code, which we have inherited equally from our biological mother and biological father. If we analyse the samples of the possible grandparent(s) to a child, we would expect to find these common maternal or paternal genetic markers which can in turn be used to determine if individuals are related.
For such 'complex' tests, we would strongly recommend that the known biological mother of the child participates in the testing as this really helps with the interpretation of the final results and makes the results so much more conclusive. Sometimes when it is just the paternal grandparent(s) and the child participating with no parental involvement, then the results can be more 'shades of grey' than black and white and this would be the one thing we would like to make you aware of before embarking on such as test.
If the child’s mother takes part in the test, it enables us to identify the mother’s DNA inherited by the child and take it out of the equation, leaving only the DNA inherited from the paternal side to be compared against the other test participant(s).
A paternity test would give the most conclusive results, but this can only be carried out if we can obtain DNA samples from the alleged father.
Please select the test you require from the below options, depending which individuals are available for testing.
Relationship testing can be a life-changing event and we would urge that before ordering a test you think carefully about the potential outcomes and have considered if testing will be in the best interests of those involved.
Please note that this at-home test is for personal information only - this means that the results will not be accepted in UK courts by the Child Maintenance Service or any other legal body.
Child & 1 grandparent
Enables DNA testing to be used by grandparents to establish their relationship to a child if the alleged father is not available for a DNA test. Mother advised to participate at no extra cost.
