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.

A sibling test can verify if two people are likely to be full or half siblings. It is impossible to determine with 100% certainty whether two people are siblings without having one or both of the parents involved. However, DNA tests can tell if two people are likely to be biologically related. It’s a test that can be requested by a parent or the siblings themselves (if they’re over the age of 18 or a legal guardian is giving consent for the minor(s) involved).
How We Produce Accurate Results
You do not need DNA from a parent to do a sibling test, however if you do have a parent willing and able to provide a sample, it will produce more accurate results. If a mother is unable to participate in the DNA test, a grandparentage test may be more definitive.
This is how it works in all relationship DNA tests – the more people willing and able to be tested, the merrier (and the more accurate the test results)!
What Types Of Sibling DNA Tests Can We Do?
- Full siblingship – if you and your sibling know you share the same mother but want to check if you share the same father (who is unable to get tested). We can also run this test if the mother is unable to participate. (However, her participation will significantly increase the accuracy of the test.)
- Half siblingship – if you and someone else know you have different mothers but want to see if you share the same father (who is unable to get tested). If one or both moms will participate in the test, the results will be more conclusive; however, parental participation is not a requirement for the test to be run
Once all samples have been collected, results should come within 5-6 days. Contact us so we can get the process started for you!

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.
How Does A Sibling Test Work?
As an individual, 50% of your genes came from your mother and 50% came from your father. If you have a full sibling, they too received 50% from your mom and 50% from your dad.
But unless you’re twins, you don’t look alike! That’s because genes express themselves differently in people.
Let’s pretend a gene is like a dice. It’s one block with six different sides. (In genetics this is called an allele. Although, genes don’t necessarily have 6 variations. This is just an example.)
When a child is conceived, it’s like both the mother and father rolled the dice. For you, say the dice landed on a 2 and that’s why you have brown hair… but for your sibling it landed on a 4 and that’s why he’s a redhead.
Although you and your sibling have genes expressing themselves in unique ways (one shows a 2 and the other shows a 4), you received the same set of genes (the same dice were rolled) from the same two people and DNA testing can verify that.
In the case of a half sibling, you won’t have as many genes in common. However, DNA tests can look and see if there are enough matching genes to prove you share a biological mother or father.
Test Smartly Labs can work with any family situation to help get siblings tested. To get started, contact us.

- 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?

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.
