We offer two types of grandparentage tests
A grandparents test allows us to the DNA of alleged father’s parents and tell you whether these individuals are genetically related to their grandchild/children and thus, whether the children tested are children of their alleged, biological father.
Duo grandparentage DNA test: This is the ideal test as it allows us to reconstruct both grandparents genetic profiles and have a fuller insight of genetic inheritance patterns in relation to the child.
Single grandparentage test: Grandparentage DNA testing can be done with a single grandparent albeit with less accuracy. In a single grandparents DNA test we strongly recommend addition of the mother’s sample.
Note that if the test involves alleged grandfather and male grandchild, we can confirm their biological relationship with a Y chromosome test.
You results will show the probability of a biological grandparentage which will be expressed as a percentage.
Cost and turnaround time
The grandparentage test is offered at $299 for grandmother, grandfather and grandchild. Your results will be sent by email in 5-7 business days, unless you specify otherwise.
