Grandparent DNA Test
What Is A DNA Grandparent Test?
Grandparent DNA testing is an advanced genetic science that helps determine the biological relationship between grandparents and their grandchildren. A grandparent DNA test can help prove who a child’s father is when the father can’t do a paternity test. When this is the case, at least one of the suspected father’s parents must be willing to use their DNA. In this process, we compare the DNA to a potential grandchild. To find out if their son is the child’s father, people use an at-home grandparent DNA test kit.
Parents give half of their DNA to their children, making up their genetic profile. The child gets half of their DNA from their mom and half from their dad. When the child becomes a parent, they also pass down half of their DNA to their own child. So, we can figure out that 25% of a grandchild’s DNA comes from each grandparent.
Sometimes, both grandparents and even the child’s mom want to be part of a grandparent DNA test to prove paternity. But there are times when the other grandparent or the mom can’t take the test. When you use the DNA of just one grandparent, there’s less information available for comparing with the child’s DNA.. We have taken this into consideration in our process. Journey uses at least 24 genetic markers for our testing instead the usual 16 markers. This gives the strongest results.
How Accurate Is A Grandparent DNA Test?
All of our testing results are 100% accurate when they are provided to you.
Our DNA grandparentage process begins with a base of 24 genetic markers. If we cannot obtain a conclusive result at that level, we will automatically enhance the number of markers examined in your DNA samples, potentially up to 46 markers. It’s important to note that there is no extra charge for this adjustment, even if additional tests are needed alongside the grandparent test. We refrain from releasing reports until the laboratory is confident that the most accurate results have been achieved. All grandparent DNA test results undergo a thorough review by a Ph.D. expert, who confirms the findings and signs the report.
Prove Paternity With Grandparents
A paternity test is referred to as an “exclusionary” DNA test. What this means is that the result provides a yes or no answer to the question if a man is a biological father of a child. The Grandparent DNA test, since it does not test the father and child directly, has the results are based on the statistical probability. Your report will show a probability that the relationship exists. The probability is stated as a percentage in the DNA results report. This percentage ranges from 0% to 99.99%+. Rest assured that the probability presented in your relationship description is guaranteed to be 100% accurate.
It’s a good idea to add the mom’s DNA if possible. This way, we can remove her DNA from the DNA sample of the child(ren). But if the mom’s sample isn’t there, or you don’t want to use it for privacy reasons, we can still do the test. We’ll just adjust how we do it, using only the grandparent(s) and the grandchild. Sometimes we need to examine additional DNAmarkers, and this may take an additional day. There is never an additonal cost if we need to change the testing to add additional markers.
Home Grandparent DNA Test Kit
We have two types of grandparent testing: one for legal reasons and another for doing it privately at home. The private test gives the same results as the legal one. The only difference is that it doesn’t have the official proof of identity needed for court.
Our at-home kit for grandparent DNA testing has four simple mouth swabs. These swabs are created to collect a small DNA sample from each person, and they are entirely painless. The cells in the swab have lots of genetic information called DNA inside them. DNA stands for deoxyribonucleic acid. We rush ship our kit to you by USPS Priority mail. They usually arrive in 1-3 business days, depending on where you live. Need us to send more than one kit to different addresses? Just indicate that when you place your order. More than half of our tests involve individuals who are located in different places.
We will provide you detailed instructions for using the mouth swabs (painless and quick). In addition we will also provide you with a prepaid overnight FedEx label to return the samples to our lab. You will be notified when they all arrive. Testing starts once everyone’s DNA is in the lab.
Deciding Who Will Be Tested In A Paternity Test With A Grandparent
Many times both grandparents, and even the child’s mother, will want to be included in a paternity test using grandparents. However, as stated earlier, there are many reasons that the other grandparent, or the mother, is not available to test. Using one grandparent for testing means that there is less genetic material to compare with the child. If the mother’s sample is not available, or you do not wish to include it for privacy reasons, we can still do the testing, and will adjust our process for only a grandparent(s) and grandchild.
We have taken that into consideration when determining the best way to obtain the answer needed from this DNA test. Our company insists on using a minimum of 24 genetic markers for the testing. This is instead of a a standard 16 marker test. These additional markers allow us to deliver the strongest result.
We mentioned prior that there are two categories of paternity test with a grandparent: legally admissible and private (at home) tests. The results you receive from our private home DNA testing will show the same results as our court admissible test, but does not include the legally necessary chain of custody proving the identity of each person testing.
Legal Grandparent Testing
Many people frequently ask if the results of home tests can serve as evidence in a court of law. Although the results from at-home DNA tests are entirely accurate, they are generally not admissible as evidence in court. In a legal setting, it’s essential to follow particular procedures for a test to be accepted as evidence. This is primarily due to the absence of a well-documented chain of custody for the DNA samples.
- Collected from an independent DNA collector not known to those testing;
- To verify the identities of the individuals undergoing testing, it’s crucial to establish a thorough chain of custody.
- Tested and reported from an AABB accredited lab;
- The custodial parent or legal guardian will need to give written consent.

|Additional DNA Collection Test Kits with Prepaid Labels
If you prefer not to receive a kit for privacy or other reasons, you can make your own kit. We’ll email you a case number and step-by-step instructions to collect and send your DNA samples to our lab for processing. If you are in the U.S.A. we also provide an overnight return label for your DNA sample.
FAQs About Grandparent DNA Testing
If the child at question is a male, and the grandfather is available, we suggest you test male to male. When testing 2 males for a relationship DNA test, they have the extra advantage of including Y chromosome testing, if it is necessary. Y chromosomes are an exact match down the male lineage.
If the grandfather is not available, the lab makes the necessary adjustments to test a grandmother and possible grandson.
When the child in question is female, a DNA test with either the grandmother or the grandfather can typically provide sufficient and accurate results in most cases.
It is very common for those who are taking a DNA test to live at a distance that makes it not practical to get together and do the DNA collection together. We provide an an option on our order form to have additional DNA collection kits sent to additional addresses.
To order additional kits, simply select the number required on the order form and provide the corresponding addresses in the designated section for the shipping destination.
We connect our DNA kits through a shared case number. After all the samples have arrived at the laboratory, our team cross-references them using the unique case number assigned to your particular case. We will notify you once all samples have arrived and testing has begun.
Yes. If you are needing a DNA test for death benefits, immigration, probate, or to prove the relationship to the IRS or other government agencies, then you will need to a legal Grandparent DNA test. If the grandparents are alive and willing to take the DNA test, they are excellent choices, especially if the father is no longer alive. It is best to add the biological mother to the testing in these situations, if possible.
Yes! Alternate samples are very common to use when you want to have the testing run in a very discreet way. To learn more about this option, click on Alternative DNA Samples.
We believe that open and honest communication is always best.
If you are looking for personal information using our at-home Grandparent DNA kit, you can discreetly and privately perform the test between the grandparent(s) and grandchild, without anyone else being aware of it.
If you are needing a legal DNA test, then the custodial parent or legal guardian will need to give written consent.
Yes! Only the person who orders the test has access to the information. We never discuss results with anyone else to ensure your privacy.
Unfortunately not. Grandparent DNA tests primarily concentrate on identifying genetic matches with the other individuals undergoing testing.
