What Is A Grandparent DNA Test?
Grandparent DNA tests compare the genetic DNA of two or more individuals to determine the statistical probability of whether the alleged grandmother and/or grandfather share a biological relationship with the tested child or children.
A Grandparent DNA test can establish paternity indirectly by analyzing the alleged father’s parent(s') DNA against a possible grandchild. This is very helpful when the alleged father is unavailable or unwilling to perform a paternity DNA test.
When possible, we recommend you use both grandparents to fill in the blanks for the missing alleged father. However, only one grandparent may be used if both grandparents are not available. It's also helpful to include the mother of the child (FREE) if possible to help the conclusiveness, or you may consider upgrading to the 46 marker grandparent DNA test.
It's important to note that not all grandparent DNA tests are the same. In fact, some entities offer cheap $99 grandparent tests that analyze a very limited number of markers, only 16-22. While the cheap DNA price may be enticing, those tests may not reach the level of conclusiveness you desire, because grandparent DNA testing can be complex.
There are 2 things that will help a grandparent DNA test achieve the best & most conclusive answer, adding the mom(s) and/or analyzing more markers.
We offer 2 grandparent testing options:
24-34 Marker Test – Our standard grandparent DNA tests add the Mom FREE & analyzes 24-34 markers, not just 20-22 like our competitors, and is competitively priced at just $125. This kit offers FREE & FAST delivery both ways.
46 Marker Test – Our premium 46 marker DNA test for grandparents analyzes 46 Markers, which is almost 300% more markers than the standard 16 marker grandparent test, and more than 2X more markers than competitors' 20-22 marker grandparent tests offered online.
This premium grandparent kit is likewise very competitively priced at $175, and offers FREE & FAST delivery both ways to your home or office.

How Accurate Is A Grandparent DNA Test?
A grandparent DNA test is 100% accurate, and can be performed with only one of the grandparents (Both Grandparents Preferred) and an alleged grandchild. We strongly recommend however, that the mother or known parent of the child take part in the analysis as well, if at all possible. This will increase the conclusiveness of the results.
Each person inherits half of their DNA from their mother and half from their father. When the known parent participates in the analysis, they are compared to their child. The DNA inherited from that parent is eliminated from the child's genetic profile. As a result, we are able to identify and isolate the DNA from the other parent in question.
If both the alleged grandmother and grandfather take part, we are able to combine their profiles to reconstruct the father’s complete genetic profile. This test is a great option to consider when the child’s mother is not participating.
In some instances, for conclusive answers, you may also choose to run the extended analysis which will compare up to 46 markers for the most conclusive answer.
How Does The Testing Process Work?
Ordering/Shipping:
Upon receipt of your online or phone order, we will rush you a FREE sterile grandparent DNA testing kit that contains all the needed swabs along with a pre-paid & pre-addressed envelope to return your samples back directly to lab. Tracking numbers are available both ways.
Sample Collection:
DNA sampling is painlessly done through a cheek swab by simply rubbing what looks like an oversized Q-tip along the inner cheek and gum and inserting the swabs in the provided sample envelope.
Sample Analysis:
When samples arrive at lab, you will be notified via email, and the true science begins. The lab analyzes the genetic profiles of the possible grandparent/grandchild and will come up with the grandparent DNA index. This is a ratio that is used to determine the likelihood of the tested parties being related.
A grandparent DNA index greater than 1.0 indicates there's a higher likelihood the tested parties are really related as grandparent - grandchild.
A grandparent DNA index of less than 1.0 indicates the tested parties are less likely to be related as grandparent - grandchild.
Therefore, the higher the grandparent DNA index value goes over 1.0, the stronger the evidence is indicating that the tested parties are biologically related as grandparent - grandchild.
To make our results easy to understand, this grandparent DNA index number is also translated into a percentage of probability from (0-100) which provides a much easier way to interpret the test results.
A test result that has a percentage of probability greater than 90% is considered a conclusive positive outcome, whereas a percentage less than 10% is considered a conclusive negative outcome.
Results Reporting:
At the conclusion of the test, the results are immediately emailed and/or mailed to the address on file.
