Accurate & Most Trusted Grandparent DNA Testing

So many entities are offering grandparent DNA tests, which laboratory should you choose? Our lab performs 3 out of 4 private grandparent DNA tests in the USA.  Many entities on the internet do not really perform their own DNA tests.  In fact, most just send their grandparent DNA tests to be performed by the lowest bidder? Often that lowest bidder is just a small out of country lab that does not follow the standards  of the AABB in the USA. Don’t buy your grandparent DNA test, without asking who is actually performing the test.  Further, you should have them show you the lab’s accreditation. If you want the most accurate grandparent DNA test results from the most trusted name in DNA, buy at PaternityUsa.com with confidence.

Quality At Home Informational Grandparent DNA Testing

Our quality premium home grandparent DNA test offers an alternative to paternity or maternity testing when the alleged father or mother may not be available. The grandparent DNA test determines a statistical probability of whether or not the tested grandmother and or grandfather share a biological relationship with the tested child or children. Grandparent DNA testing is often used to indirectly establish paternity by testing the alleged father’s parent(s) against a possible grandchild.

Why Risk Using Your Own Q-tips® – We Overnight A Sterile Collection Kit To You For Free

Our grandparent DNA testing package is complete with testing kit, DNA analysis and test results. Some companies advertise that you can make your own collection kit by using your own Q-tips®. However, we do not recommend this practice. There is a risk of multiple DNA samples being found on Q-tips® that are not sterile, or that may be handled by more than one person. Q-tips® you may have in your home could already have DNA from other sources on them. For this reason, we send a grandparent DNA collection kit containing sterile buccal swabs to you at no charge. We even ship the collection kit to you via FREE UPS overnight so you have your sterile medical swabs as ready for use as soon as the next day.

With PaternityUSA.com you can purchase the best quality grandparentage test in the industry at the cheapest prices. Our lab is the largest and most trusted name in DNA testing through-out the USA and even the world. All of our DNA tests are performed by top-notch geneticists using proven scientific methods and state of the art equipment in our AABB accredited laboratory. Our service is simply unparalleled and our prices are very affordable. You can rest assured your DNA samples are secure and your results will be accurate. With today’s technology and inexpensive pricing on DNA relationship testing, there is no longer a need to go without knowing the truth about a biological relationship.

How To Increase The Accuracy Of Your Grandparent DNA Testing

The grandparent DNA test may be done with only one of the grandparents and the alleged grandchild. However, we strongly recommend the mother or known parent of the child take part in the test as well, if at all possible. This will increase the conclusiveness of the test.  Each person inherits half of their DNA from their mother and half from their father. When the known parent participates in the grandparent DNA test, 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 parent in question; then compare that DNA to his or her possible parent, the grandparent, giving a more conclusive result.

If more than one grandparent is able to take part in the test, combining the two known parents of the alleged father provides the father’s complete genetic profile. This test is a good option to consider when both grandparents can test, or the child’s mother is not participating in the test. Although this test is conclusive, adding the child’s mother to the test reveals the complete genetic footprint. This type of testing produces a result as conclusive as a paternity test.

When Test Participants Are Both Male Or Other Relatives Are Available To Test

In a scenario where the alleged grandchild is a male and the paternal grandfather is able to take part in the DNA test, a Y-STR test will conclusively determine whether or not they share the same male lineage.

On the other hand, if a relationship is trying to be established on the mother’s side, an mtDNA test will offer a conclusive answer regardless of gender.

Other relationship tests may also help establish paternity or maternity, such as a Siblingship test, or a Aunt Uncle DNA test with one or both of the alleged parent’s biological siblings.

Additionally, if there are other paternal relatives able to take part in a DNA test, such as a known sibling to the alleged father, a Family Reconstruction Test offers a combined probability of the relationship to the family members.


When Participants Are In Different Cities Or States

It isn’t uncommon for test participants to live too far apart to get together and do the DNA collection.  We offer an option to have multiple collection kits shipped out for these situations. When ordering, simply choose the option for an additional address. We will send each collection kit via overnight UPS. If you purchase the 2 day return mailer, we include it for all addresses on your order. The collection kits are linked through reference number and bar codes. When the samples are received back in lab, they are matched to your case through the bar code and reference numbers.

Grandparent Testing Process And DNA Sample Collection

The grandparent DNA testing process is very simple. DNA is collected on a cheek swab, also called a buccal swab. The swab is painlessly rubbed against the inside of the cheek. In this process, skin cells collect on the swab.We conduct all of our tests twice. For that reason, there will be 4 buccal swabs per person in your collection kit. Do two swabs on each side of the mouth. It is best to rinse the mouth with water and refrain from smoking or drinking coffee or tea for 2-3 hours before the DNA collection. Once the swabs have been taken, place the samples in the return prepaid pre-addressed mailer. Finally, simply drop the samples off at the courier’s location or box to send your kit back to the lab for testing.

When all samples are in the lab, you will be notified via email that testing has begun. We will email the results of your grandparent DNA test when the testing is complete, within 3-5 business days. If hard copy results are ordered, the report is sent to the billing address unless otherwise noted.

We ship our collection kits with free UPS overnight delivery Monday through Friday to physical addresses in the contiguous USA. Orders received and processed by 2:00 PM EST are shipped the same business day. Orders received after 2:00 PM EST are shipped the following business day.

When You Need A Legal Or Immigration Grandparent Test

Informational grandparent DNA testing can provide you with the peace of mind of whether or not a biological relationship exists between the tested participants. If you need the results of your grandparent DNA testing to be admissible evidence in a court of law or other governmental domestic agency, then purchase our AABB accredited legal grandparent DNA test. Our legal grandparent DNA test results can be submitted as evidence in child support, visitation rights, change name on the birth certificate, estate, wills, probate situations, and/or any other type case where the relationship of the tested parties must be proven by an AABB accredited DNA test. If your DNA test is for immigration purposes, the USCIS/ICE & Dept. Of Homeland security may require AABB accredited DNA evidence of the grandparentage relationship. If so, then order our AABB accredited DNA test for immigration purposes.

Forensic DNA Samples

The most common method of DNA collection is through a cheek swab. However, we understand there are times when test participant is unable to submit a swab in a grandparent DNA test, such as may be the case when a family member may be deceased, incarcerated or otherwise unavailable.  For these reasons, we offer forensic processing services for other types of DNA samples. Ear wax, hair (must have the root ball attached), mucous on a tissue, finger or toe nail clippings, and toothbrushes are common forensic samples. Additionally, in certain cases tissue and/or blood samples may be available from a medical examiner or coroner’s office. Forensic sampling prices apply for any non-standard DNA sample. For pricing and more details on the process, please contact a DNA Case Manager.

Awesome. Easy. Best Price Around! Got my son's birth certificate right now. Thank you all!

I purchased this Y-STR test to verify that my son is the father of my grandson. Now I know for sure this sweet little boy is my son's baby. Thanks Paternity USA for the peace of mind.



I took this test last month and my results were accurate. Easy process, good customer service and i like that they notified me of the status of my case all along the way. I always wondered and now I finally know for sure. I highly recommend you all every chance I get. Lisa L

I picked paternity usa for my immigration test for my mother and sisters. I'm so glad I did. Everything great - very good service and fast.

I don't usually write reviews, but I feel like this one is important. To have a lingering question of whether you belong in a family or not isn't anything easy to deal with. I wondered at first, because they are cheaper than everyone else, and felt like this is an area I shouldn't skimp on, but I'm so glad I picked these guys. I didn't skimp - I just found the best deal! My test result was very definitive and left no room for question. I want to let others know that you can find your answer and peace. Pick Paternity USA, they will do a great job. I can't say enough good about them. Thanks - Brenda

I am glad I chose this company for my paternity test. They scheduled an appointment for me and my daughter, it was within a couple of days, then the results were emailed to me less than a week later. I didn't have to do anything but show up for the appointment - they handled everything else from beginning to end.

J Luna


Thank you guys for a process that is easy and quick. You've been so helpful! Jenn



I was given up for adoption and found a sibling through online records. We did the mtDNA test to see if we have the same mother (who is deceased), and I finally have been able to connect with my family. Even though I will always be thankful to my adoptive family, it's nice to add to that! Test was conclusive, process easy and good communication. Thanks 🙂

I called PaternityUSA to help us with getting my children in from Jamaica, and so they performed the AABB accredited DNA test for immigration. The process only took (2) weeks, and everything was very smooth. I cannot thank these people enough.


Peter Johnson

I had bought a DNA kit at CVS pharmacy, but I wanted to see if I was the grandparent. I discovered that I could not use the drug store kit for a grandparent DNA test. I called paternityusa, and I'm very pleased with the work they performed. They really took the time to talk to me
