If you’re trying to determine someone’s biological father (or mother) and the suspected parent is unwilling or unable to be tested, you may be able to test grandparents for a “probability of grandparentage.” Grandparent testing may also be used to confirm a biological family relationship between a child and extended family—if the child is a minor, the legal guardian must give consent. A single grandparentage test can be performed if only one grandparent is available for testing, but the mother must be included in this case.
How Does A Grandparent DNA Test Work?
The way DNA works is you inherit one half of your DNA from your biological mother and the other half from your biological father. Your mother and father also received their DNA in the same way, so their biological parents will carry the same genes that trickled down, and testing them can confirm biological relationships.
All of us carry a quarter of our genes – 25% – from our grandparents. That’s why, although it’s not as strong as a paternity or maternity test, a grandparent test can still look for DNA matches and offer a probability of biological relationships.
You do not have to be local for us to perform your DNA testing. We can arrange collections across the United States. Once all samples have been collected and sent in, results should come within 5-6 days.
Just let us know, and we can get you started on this process as soon as you need.

Understanding the Downside Risks of “At-Home” Non-Legal Paternity Tests
Everyone is well aware of the fact that genetic material comes from both parents. The mother’s and father’s genes come together to form the unique chemical which is generally known as DNA.
Discovering Your Past, Learning Your History, and Uncovering your Heritage
When many people think of laboratory blood tests, they imagine making an appointment at their doctor's office, taking time off work, paying large fees, and waiting around in the lobby for who knows how long.
What needs to be collected?
To run this test, we will need to collect samples from:
- One Child
- Both Paternal Parents of the Alleged Father
It’s important to note: for a test to be used as defensible evidence or for any legal situation, the test must be collected, analyzed and reported by us – no do-it-yourself DNA kits will hold up in court because identities are not verified and proper collection procedures cannot be documented
We only use AABB-accredited labs, which means we uphold the highest standards in DNA lab testing.

Be prepared for your DNA or Paternity Test!
- Bring Government Issued ID
- Bring Birth Certificate for Child. If none, bring a social security card, insurance card, or something else to help support identification.
- Complete TSL Intake Form & HIPAA Disclosure
- Provide Authorizations to Receive Results
- Most DNA will require a Buccal Swab specimen from the mouth
- Prenatal DNA will require a Blood Draw so you will want to by hydrated
- Be prepared to have a photo taken of all parties being tested.
- Do not eat anything (particularly meat, vegetables and breast milk for infants) for an hour before arriving.
- You do not have to arrive together or go to the same Test Smartly Labs Testing Center but do coordinate plans with all parties being tested.
What Are Your Hours?
- All Test Smartly Labs are open Monday through Friday, from 9am - 5pm
- The Overland Park Testing Center is also open from 9am – 1pm on Saturdays
Do We Need To Have An Appointment?
- No appointment is required to come into our labs, and all of our locations are on a walk-in basis. However, it is recommended you arrive at least 30 minutes prior to closing. If your situation requires special time considerations, please call us to determine if it would be better to arrange an appointment time.
Do I Need Doctors’ Orders For Testing?
- No doctors’ orders needed, we are a Direct-Access Testing Center. You are encouraged to consult your medical professional with your lab test results.
What’s The Turnaround Time For Lab Work?
- Average turnaround time is 2-5 business days depending on the complexity of the lab work. Most tests are available in 2-3 days.
Do You Need A List Of My Medications For A Drug Test?
- Per protocol, the lab techs are not allowed to receive or ask for your medications. A medical review officer or MRO, a licensed physician who specializes in toxicology, will call you and ask for your medications and your physician’s phone number if it’s detected in your sample during testing. The MRO will then call your physician to verify your medications.
