Legal Grandparent DNA Test
Health Street's Legal Grandparent DNA Test provides a reliable, court-admissible way to establish paternity or other family relationships when the alleged father is unavailable. This legal test is often used in cases where the father cannot or will not participate, but at least one paternal grandparent is available for DNA collection. Our relationship tests deliver conclusive results you can trust for legal purposes, such as child custody, social security, or inheritance claims.
The parties can be tested together at the same time and at the same clinic, or they can be tested separately at different times and/or at different clinics. This can be very helpful when the parties live in different states. Upon scheduling your tests, we will email you with your appointment details. Register online or call (888) 378-2499.

“ Fast, Professional DNA Service ”
Got in fast. DNA was done quickly, even with a squirmy baby. My results did get lost in the mail because of the holidays. Luis helped me right away, order new ones. He didn't question me, he understood and empathized with my concerns, and got another packet out in the mail for me right away. I loved how they turned something that could have went very badly, into a great experience. Very professional. You can't go wrong. We did a DNA with a male child and paternal grandfather!

$550Frequently Asked Questions
Below are the most commonly asked questions about this product in our call center.
What is grandparent testing?
Grandparent DNA tests, also known as grandpaternity tests, are used to identify the biological relationship between a child and an alleged father without having to test the father himself. We use DNA samples from the child, the mother, and at least one of the child's paternal grandparents. This test is court-admissible and is typically used for legal reasons such as child custody, inheritance, immigration, or social security.
Do you offer home kits for grandparent DNA testing?
Yes, a $450 home kit is available for peace of mind only. It includes:
-
Cheek swab kits for both grandparent and grandchild
-
Prepaid FedEx overnight return label
Note that home tests are not legally admissible.
Can I pay just for my half and have the other party pay theirs?
Yes. You can pay half up front, and the other party can call in and pay their share separately. Scheduling will not be finalized until both parties have paid.
Can law firms pay for the test on behalf of their clients?
Yes, but payment must be made by debit or credit card at the time of booking. Health Street does not invoice or bill law firms.
How much does a legal grandparent DNA test cost?
-
In-lab, court-admissible test: $550 total for one grandparent and one grandchild. If separate appointments are needed, there is an additional $50 fee.
-
Home kit (for peace of mind only, not for legal use): $450
Attention NY Residents: A doctor's prescription is required for all DNA tests; additional lab fees must be paid directly to the lab.
How do I order grandparent DNA testing?
Book your appointment online or call us, and we'll set it up for you. Our scheduling department will make your appointment based on your preferences for when and where you would like to test. The parties can test at the same time in the same location, or separately at different locations nationwide.
How are DNA samples collected?
Samples are collected using a buccal swab, which is a soft cotton swab rubbed inside the cheek. This method is quick, painless, and highly effective for DNA analysis.
What should I expect at the DNA appointment?
You can change your appointment or location at no additional charge. When you arrive for your test, all adults must present their photo ID. If the child is under 18 years of age, they can be identified with their birth certificate or social security card. For a newborn, use hospital discharge papers.
How do I get my results?
In most cases, after all specimens have been collected, the turnaround time is about one to two weeks for you to receive your results. First, we send your test results via email and through our GLASS portal, and then we'll send a signed hard copy from the lab through the U.S. mail.
Is there usually a waiting list for appointments?
No, appointments are usually available on business days (Monday through Friday). Same-day or next-day appointments are often available.
Do the people being tested need to be in the same location?
No. For an additional $50, parties may choose the location and time most convenient for them. Our clinics are nationwide.
Are the results legally valid?
Yes. Our legal tests follow strict chain-of-custody procedures using AABB-accredited labs, making the results admissible in court and for other official uses.
About Our Legal Grandparent DNA Test
Legal Grandparent DNA Test
If you need DNA test results for a legal purpose, such as for the child to collect social security benefits or so that you can change their birth certificate, the specimens must be collected at one of our clinics. Courts will not accept results from home DNA collection kits.
We have thousands of convenient locations in the U.S., and we offer flexible appointment scheduling. The grandparent(s) do not have to test in the same location as the child and his or her mother.
Why Get a Grandparent DNA Test
You may be trying to establish paternity for legal purposes such as child custody or child support, but the man is not available to be DNA tested, possibly due to an unwillingness to be tested, incarceration, or death. A Grandparent DNA test is a good alternative to determine the father when paternity tests are not an option.
Here's how it works: we need at least three of these four people to provide a DNA sample using cheek swabs:
-
Child
-
Mother
-
Paternal Grandmother and/or Paternal Grandfather
If both paternal grandparents are available for testing, that's even better. If the mother does not agree to be swabbed, then we require both grandparents. By establishing the grandparent-grandchild relationship, the paternity of the alleged father can be imputed.

Happy with Company
Im happy with the company and the person whom booked the appointment, however, the lab core personnel was not friendly, acted like they didnt no what to do and made me feel very un easy at the apt. My grandson cried the entire time we were in the office , my point is that babies yes cry but even his senses picked up the worker was not friendly. Im glad the test was sent to you ... I would not recommend this location to anyone. Let me say again the customer service to set this test up was nice informative an answered all questions. The staff at lab core shows they are not happy with there job!
