Finding Biological Grandparents Using a DNA Test

A DNA match list is a type of clue that helps you learn more about the biological relationship between two people. Therefore, finding grandparents is much easier with a paternity test, especially if you have parents, maternal or paternal uncles or other similar relatives. In this case, even the DNA of the first and second, or even half-cousin, will be useful.

Most of any person’s paternal and maternal lineage can be determined based on DNA testing results. Here the original DNA sample will belong to a third, second, or even first cousin. The original DNA will be compared to the suspect’s DNA to determine if there is some similarity in DNA sequencing, and if so, the overall percentage of similarity in both DNA.

Grandparent DNA Test Accuracy


Experts estimate that DNA testing between grandparents and grandchildren is 100% successful. The test does not require samples from both grandparents, and a sample obtained from one grandparent is sufficient to verify the desired results using comparative tests. The best way to obtain accurate results in this testing option is to use samples from both the parents and offspring of the older adults concerned.
