The results of a sibling paternity test are shown as a probability percentage. This indicates whether the genetic profiles acquired can confirm the presence of a relationship. Results demonstrating a probability of 91% or higher are deemed as definitive proof that the relationship exists. Conversely, a probability of less than 9% establishes that the genetic evidence does not support the existence of the relationship.
The answer is "Yes" in almost every situation. A sibling DNA test can determine which brother is the biological father of a child, if you include the DNA of the mother. Every child has genetic contributions (46 chromosomes) 23 chromosomes from the mother and 23 chromosomes from the father.
Yes, our DNA test can prove you are half siblings. In fact, DNA testing is the most scientific and accurate way to prove that two or more individuals are biologically related. Half-siblings share only one biological parent, either the mother or father.
We offer AABB accredited legal sibling testing which is valid in cases for child support, parenting time, birth certificate name changes, probate, and wills, as well as many other legal circumstances. A legally admissible DNA test requires some extra steps, however the final results will be the same.
It depends. Since half siblings share 25% of the same DNA, and first cousins share 12.5%. Depending on if a mother's DNA is available to test as well, there may be other testing options that would give stronger results. In these situations we encourage you to talk with one of our Genetic Consultants at 1-855-362-5224, or email us at firstname.lastname@example.org and we can offer advice on your unique situation.
Yes! Some commonly used items that are not a mouth swab include ear wax, hair (must have the root ball attached), mucous on a tissue, finger or toe nail clippings, and toothbrushes. You can learn more about these "non-standard" DNA samples by clicking on Alternative DNA Samples, or call us a 1-855-362-5224.
If you place your order before 2:00 PM PST, we will send you a sterile DNA collection kit by Priority mail and email you a USPS tracking number.

Depending on your location, USPS delivers Priority mail within 1-3 business days.
Once the lab has all of the samples available for sibling testing, we will have the results for you in 2 business day in almost every single case. All DNA tests for siblings are performed twice, to validate the findings. We do not charge any extra fees for this service.
You can still do DNA testing without a mother's DNA. What if you can't provide her sample with the siblings' tests? We can still proceed, but we might need to examine more genetic markers. We begin with 24 markers, but sometimes we use up to 46 for stronger results. While this isn't common, it's possible. We'll determine the need during testing. Additional markers might take an extra lab day, but no extra charge. These added markers aim for the best results.
The mouth (buccal) swabs are packaged in sterile packaging. You will have two packets. Each packet contains TWO swabs. You will use all 4 swabs for each person.
Step 1: Complete the information on the DNA collection envelopes. The names listed should be the same as you put on your order form. There will be one collection envelope for each person whose DNA is being collected.
Step 2: Open the paper packaging and remove the swabs. Please be careful to handle the swabs on the long handle (the non-cotton end) only. DO NOT, at any time, touch the cotton end with your hands or fingers.
Step 3: With clean dry hands, collect cheek cells by rolling the tip of the sample collection swab firmly on the inside of the right cheek and under the tongue for 20-30 seconds. Be sure to roll the swab over the entire inner cheek surface. Repeat this process for the same individual with the second swab. You should use two swabs on the inside of the right cheek and two swabs on the inside of the left cheek.
Repeat the process for every individual being tested using a different set of swabs and envelope for each person.
Step 3: The mouth swabs should be dry before putting them into the collection envelope. The best way of doing this without risking contamination is to place them in an upright position in a clean dry glass. Do not put more than one person's DNA samples into a glass at a time. The DNA samples of each person must never touch each other. Once they are dry, place them back into the correct envelopes.
Step 4: Place all of the swab envelopes, plus and any included forms that you have completed, into the large pre-paid FedEx return envelope. Then simply return them to a FedEx office or call FedEx to pick it up at a time that fits your schedule.
Your DNA test results will be easy to read and understand. We will also provide you with our "Understanding Your DNA Results" booklet.
We are providing examples of sibling DNA reports below to give you an idea of what the results you receive will look like. Examples of non-legal and legal test results are included. The results are the same for both home and legal tests, however the legal tests require professional DNA collection, and are notarized,
The following example report shows results that indicate a HALF SIBLING compared to a NO SIBLING relationship. In this case, the genetic evidence shows they are half siblings.
In the next example, we have a DNA test result indication two siblings who know they have the same mother are confirmed as full siblings.
Next, we are providing an example of two people who do not have the same mother, and are testing to see if they have the same father. This would make them half siblings. In this result, we see that they are not half siblings.
Finally, here is an example of a full sibling vs half sibling test that indicates the two siblings do not share the same father.
As you can see, the reports provide the information needed to know if those testing are full or half siblings. Once you get your DNA report back, if you have questions, we are happy to provide you with help if needed.
