Grandparent DNA Test
Grandparent DNA Testing – $129.00 – Results in 2 days!
When an alleged father (or mother) is not directly able to be tested, at least one of the suspected father’s (or mother’s) biological parents can perform a DNA grandparent test to help determine if he or she is the true father or mother of a child.
Biological parents equally contribute 50% to their child’s DNA, so that one-half of his DNA comes from each parent. When that child becomes a parent, they in turn contribute half of their DNA to their child. Therefore, 25% of the grandchild’s DNA comes from each grandparent, through their biological child.
There are times or reasons that the other grandparent, or the mother, is not available for the grandparent testing. This is why we insist on use 24 genetic markers for the testing, to deliver the strongest result. The results we provide for our informational testing is the same as our court admissible testing, just without the legal paperwork. Adding the mother’s DNA sample, if possible, will allow us to eliminate her contribution to the child and then focus only on the paternal contribution if trying to establish who the biological father is. There are some instances where the probability of relationship may be stronger if including the mother’s DNA sample. We do not charge for the mother’s sample if included at the time of the initial order.
If the mother of the child is not available, or you do not wish to include her sample, we can still perform the testing between the grandparent(s) and the possible grandchild. In these cases our testing lab makes a mathematical and scientific adjustment in the testing process which allows for only one grandparent and one grandchild being tested with results that are accurate, clear, and understandable in almost every case we handle.
We guarantee the most accurate DNA Grandparent test available.
Grandparent DNA testing is based on the statistical probability that two or more people are related by bloodlines as grandparent and grandchild. The industry standard for testing of this type compares 16 alleles to attempt to arrive at the conclusion if a grandparent/grandchild relationship exists.
The challenges and limitations with this approach is that when using so little genetic material, it is very difficult to arrive at a conclusive result because a grandparent only shares up to 25% of the same DNA with their suspected grandchild. All humanity shares 99.9% of the same DNA, which means that only .10% can be used to determine the answer as to whether or not a grandparent/grandchild relationship exists.
When only 16 markers are being considered, there is a very good possibility that an inconclusive result will be reported. Even worse, a false negative or false positive is also a potential outcome. Journey Genetic Testing holds the position that there are just not enough markers tested in a standard test to feel confident about the results.
Journey Genetic Testing uses up to 50% more alleles than other companies to perform the DNA testing. The DNA sample of the mother can be included at no additional charge.
Grandparent Test FAQs
No, you do not need the mother’s DNA, however it may be helpful in some cases to eliminate her DNA from the child. This occurs in about 2% of grandparent cases. We do not charge for the mother’s DNA sample when it is submitted at the time of the testing. In the event her DNA is suggested, it can be added after the testing results if desired.
If both grandparents are available to test, you may also want to consider that option, as the testing results are no different than a paternity test using the suspected biological father.
When both grandparents, or the mother,is not available our testing laboratory will automatically adjust the testing to account for one grandparent and one child.
If you are seeking answers for personal information only, then the test can be done discreetly and privately between grandparent(s) and grandchild(ren) without any other person knowing.
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. You have a private login name and password that only you know. We never discuss results with anyone else to ensure your privacy.
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 Alternative Samples click HERE.
The testing is based on the genetic profiles we obtain from the DNA samples sent for examination. The results we deliver are based on the testing process and the probability we list 100% accurate as delivered. A probability of relationship greater that 90.9% is considered conclusive proof of the relationship.
The Since the grandparents DNA profiles contain all the key components of which the alleged father and the grandchild’s DNA is made up of, the strength of the probability may be increased if both Grandparents are available. Our grandparent DNA test can be as strong of a result as a paternity test.
Many grandparents order this test because they are concerned that they might not be the actual biological grandparents of a child or children. They are rightfully concerned, and only want to know the truth. Being a grandparent requires both emotional and financial support for many years, and if there is a question about the paternity of a grandchild, the grandparents have a right to know with certainty that they are related. Aside from peace of mind, there may also be legal reasons for wanting to confirm a biological relationship if the suspected father of the children is not available.
Reasons to confirm paternity include:
- Health concerns
- Death of potential father
- Custody issues
- Heritage and inheritance concerns
- Questionable paternity of child
- Peace of mind
Yes. If you are needing a DNA test for death benefits, then it will need to be the legal DNA test. If the grandparents are still living and willing to do the DNA test, they would be great candidates if the father is deceased.
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.
If the child at question is a female, a DNA test can be done with the grandmother or a DNA test with the grandfather as either will be sufficient in almost all cases.
Unfortunately not. The genetic tests that are performed for grandparent DNA tests are only screened for the sole purpose to find genetic matches in the other individual testing against.

Grandparent DNA Sample Collection
The most accurate method of obtaining DNA for a grandparent DNA test is to use a buccal (mouth) swab, which is very similar to a “Q-tip” cotton swab. The swabs are rubbed on the inner cheeks of the mouth of those being tested. The process is simple and fast. We provide all the materials needed for the DNA collection in our Journey Genetic Testing Test Kit.
However, we know that sometimes it is not possible to obtain a buccal swab sample. We are often able to test discreet alternative DNA samples. To learn more about non-standard, alternative DNA samples that we can test, CLICK HERE.
Your DNA collection kit will have detailed step-by-step instructions on how to collect your swab sample. You can also read more about how to take a home DNA test by going to How To Collect A DNA Sample At Home.
If you need to send one or more of the DNA collection kits to a different address, we can do that as well. Just indicate how may collection kits you need when you complete the order form, and enter the addresses for each kit in the area of the form where it asks where the kits are being sent.
Making your own DNA kit (MYOK)
All orders include a DNA collection kit sent to the designated address on the order form. We understand that you may be in a situation where you do not want anything being mailed to you, to allow additional privacy.
Journey Genetic Testing allows you the option to make your own testing kit when collecting and returning DNA samples to us. This option can save money on shipping a DNA kit to you, as well as save you time as you can ship directly to us without waiting for the testing kit to arrive.
To choose this option please select the “Make My Own Kit” option on the order form for the particular test you are seeking. You will find the order form on the information page for that particular test. For example, paternity test order forms are found on the paternity page, sibling order forms are found on the sibling page, and so on.
Upon finalization of your order (during regular business hours) you will be e-mailed a submission letter with your unique Journey Genetic Testing case number and the address for mailing your samples. The processing of the samples is conducted in the same time frame as if you used one of our kits – in as little as 1 business days for paternity, maternity, sibling, grandparent, avuncular, and twin zygosity tests!
Non-standard samples being submitted must fit into a standard envelope. If necessary please trim the item to fit (for example a hat band, a piece of clothing with blood, etc) into a regular envelope while making certain the specific area to be tested is included.
DO NOT USE PLASTIC WRAP OR A “ZIP LOCK” BAGGIE FOR STORAGE OF YOUR DNA SAMPLE. THIS MAY CAUSE THE SAMPLE TO DEGRADE AND A GENETIC PROFILE NOT BE ABLE TO BE GENERATED. LAB FEES WILL STILL APPLY AS EVERY EFFORT WILL BE MADE TO EXTRACT ENOUGH DNA FOR TESTING.
It is strongly suggested that if you reside outside of the United States and wish to order DNA testing that you use this option as the most cost effective and time efficient method to get the answers you need and deserve.
Please note that we are unable to process any DNA samples without a Journey Genetic Testing case number. Samples that arrive without a case number will be discarded.
Example of Grandparent Test Results
Grandparent DNA test results will show the genetic information for all of those who submitted DNA samples for testing. This example grandparent DNA test result shows a single grandparent DNA test, without the mother, and this test shows the relationship is excluded. If the mother does not test, or if the other grandparent is not tested, the testing report does not show their names.
The DNA test report above shows the results of a laboratory DNA test that provides evidence regarding the alleged family relationship. This is a brief explanation of the meaning of the numbers that appear in a DNA test report:
The laboratory analysis tests the DNA isolated from cheek swabs to locate certain regions of chromosomes that are known to vary in length between individuals. Twenty four of these sites are tested; each site is called a “locus”, (“loci” – plural). Analysis of these 24 sites in a large population has revealed many different sized categories associated with each site. Categories of a DNA sequence or a gene are called “markers” or “alleles”. These are the genetic markers used in grandparents DNA testing.
Because each individual has two of each type of chromosome, one inherited from each parent, everyone has two alleles at each locus. These two alleles are sometimes identical (homozygous), but usually they are not the same size (heterozygous). During parentage DNA testing, the laboratory identifies the length of the two alleles found at each locus.
The DNA test report you will receive shows numbers (in the first column) that indicate each of the 24 loci involved in the DNA testing process.
A 90.9% and greater probability of relationship is conclusive proof the relationship exists. A 9.9% of lower probability of relationship means that the genetic evidence does not support the biological relationship tested for.
Our AABB legal DNA test result and private home grandparent DNA test results will look the same on the report, except that the home test does not have the word “legal” and is not notarized. The findings, the wording, and the genetic markers tested are the same.
Grandparent DNA Test Reviews
Thank you for your help and guidance
It had been over a year since I’d talked to my last living grandparent so there was tension right from the beginning. Fortunately Journey Genetic Testing has experience helping people dealt with family tensions – I don’t know how we would have got through this without your help!
I want to take the opportunity to thank you guys for the special service you provide. I have very recently found that I have a Grandson.
A worrisome time for my granddaughter and myself. Thanks to you we’ve come through it. My gracious thanks for your services team for their empathy and compassion in our case.
Great customer service!
The customer service member I spoke to was awesome!
Do you offer your tests outside of the USA?
This is one the most often asked questions we get. The answer is YES.
Legal testing collections can be coordinated in over 100 countries. Please contact us at 1-855-362-5224 to learn more information about this option. Private DNA testing is the most common type of test ordered , and so we want you to know all of your options prior to ordering your DNA test.
First, we can ship a DNA collection kit almost anywhere in the world. The only exception to that is if the country you live in, or want to have DNA testing done in, does not allow shipments from the U.S.A. or DNA testing for it’s citizens. The responsibility to know the rules of your country belongs to you.
Second, we have several ways to help you get your DNA samples to us. All of our shipments are sent through USPS (United States Postal Service. You can choose to either have the kit(s) send via USPS International Priority, or USPS International First Class. We are charged extra by the postal service for sending material outside the U.S.A,, and just pass that expense onto you. You can choose either way to have the kit shipped depending on your budget and need. International Priority may take 6-10 days and International First Class may take 10=16 days, depending on the country.
We provide you a tracking number for your shipment(s) so you know where it is at at all times. Once it leaves the U.S.A. and is sent to your county, there are some things that are outside of our control that may delay delivery. Among those are holds at Customs, an address that you have provided on your order form that is incorrect, or delays due to the worldwide pandemic. Our lab remains open and testing, but we just want you to understand what may delay your kit (hopefully not!).
There is an option that we are Journey Genetic Testing highly recommend for those clients outside of the U.S.A. We offer a Make Your Own Kit option, that is just as accurate to collect DNA sample with, and it saves the cost of international shipping, as well as time. There is no extra cost for this, and you select it when you place your DNA test order. If you are interested you can learn more by CLICKING HERE.
We will of course notify you by email once all the DNA samples arrive at the lab, We do recommend that whatever carrier your choose to return your DNA samples to the lab, that you obtain a tracking number for that carrier to make certain they arrive.
Our reports can be issued either in English or Spanish. If you need a report in Spanish we will need to know that at the time of your order.
We are excited to help you get the answers you need and deserve on your journey to truth through DNA testing!
