The DNA Sibling Test is used in situations where the alleged parent(s) are not available for testing. The DNA Sibling Test provides the likelihood that alleged siblings are full siblings, half siblings, or not related at all. Whenever the parent(s) in question are available for testing, the DNA paternity or maternity test is recommended over the DNA sibling test. However, in situations where the alleged parents are missing or deceased, then the sibling test is the next best option for investigating the relationship of potential siblings. The full genetic report is included with every test.
During a DNA sibling test, a buccal swab (mouth swab) is collected from each of the alleged siblings to obtain cells containing genetic information in the form of DNA (deoxyribonucleic acid). Each person’s DNA represents a unique “genetic blueprint,” similar to a fingerprint. In the laboratory, the DNA is extracted from the cells, and specific DNA regions are amplified through a process called PCR (polymerase chain reaction) for thorough examination. The siblings’ DNA patterns are then compared to each other. A statistical analysis is conducted based on the match type typically expected for true biologically related sibling pairs, generating a “full sibling index” and “half sibling index.” True biologically related full sibling pairs (with the same mother and father) usually have a full sibling index value greater than 1.0 in their DNA sibling test report. Conversely, individuals who are not full siblings typically have a full sibling index value less than 1.0. True biologically related half sibling pairs (with only one parent in common) usually have a half sibling index value greater than 1.0 in their DNA sibling test report. Conversely, individuals who are not related typically have a half sibling index value less than 1.0. The higher the sibling index value over 1.0, the greater the likelihood that the two individuals are biologically related as siblings. Similarly, a half sibling index value of 1.5 indicates that the siblings share more genetic material than would be expected by chance alone. Conversely, the lower the sibling index value is below 1.0, the lower the probability that the two individuals are biologically related as siblings.

Frequently Asked Questions
Why is it important to choose an accredited laboratory?
Selecting an accredited DNA testing laboratory is essential for several reasons. Firstly, accreditation serves as a mark of legitimacy and trustworthiness. It assures you that the laboratory meets stringent standards and follows established protocols to ensure accurate and reliable testing.
Accreditation also guarantees the highest quality of testing. Accredited laboratories undergo comprehensive evaluations by reputable organizations to assess their proficiency and competence. By choosing an accredited laboratory, you can have confidence in the precision and integrity of your test results.
At Genetrack, we take pride in being one of the few DNA laboratories worldwide to have received all major internationally recognized and prestigious DNA laboratory accreditations. These include the Standards Council of Canada (SCC), American Association of Blood Banks (AABB), College of American Pathologists (CAP), Clinical Laboratory Improvement Amendments (CLIA), and ISO/IEC 17025, a testament to our commitment to upholding the highest standards in DNA testing.
How does the Home DNA Sibling Test work?
Once you place your order for Home DNA Sibling Test, we'll promptly send you a DNA test kit. The kit comes complete with easy-to-follow instructions to guide you through collecting a mouth swab sample from each person participating in the test. Simply rub the swabs gently inside the mouth for 15 seconds, then send the collected samples to our laboratory for analysis.
We'll start testing your DNA samples immediately after they arrive at the laboratory, and your Home DNA Sibling Test results will be ready within just 1 to 2 business days. We'll notify you when your samples arrive at the lab, and again after your test is completed. You can download or view your results directly from your secure online account, available online 24/7.
How long does it take to get the results once you've received the samples?
Once we receive your samples, testing begins immediately, and results are usually ready within 1 to 2 business days. You can access your results securely online through your secure online account.
How will I receive my Home DNA Sibling Test results?
You can view your Home DNA Sibling Test results discreetly from your secure online account once the test is completed. You also have the option to download and print unlimited copies of your final test report.
Why would I need a DNA Sibling Test?
A DNA Sibling Test is typically used when there is a need to establish a biological relationship between potential siblings and the alleged parents are not available for testing. This could be for personal reasons, such as confirming family relationships, or for legal reasons, such as inheritance disputes or immigration cases.
Is the home DNA test as accurate as the legal DNA test?
Yes, the home DNA test is just as accurate as the legal DNA test. Both tests are performed in our accredited laboratory and use the same advanced technology and rigorous testing procedures to analyze the DNA samples. The results from both tests are equally accurate and reliable.
The main difference between the two tests is not the accuracy of the results, but the method of sample collection and the documentation process. For a home DNA test, you collect the samples yourself at home, while for a legal DNA test, the sample collection must be witnessed by a neutral third party, such as a medical professional or a legal representative, to maintain a chain of custody. This chain of custody process is what makes the results of a legal DNA test admissible in court.
So, if you need the test results for legal purposes, such as child custody cases, child support disputes, inheritance claims, or immigration applications, you would need to opt for the legal DNA test. If you're simply seeking to confirm a biological relationship for personal knowledge, the home DNA test would be sufficient.
Can the kit be shipped to more than one address if the parties live in different cities?
Absolutely! If the participants live in different cities or even different countries, we offer the flexibility to ship the DNA test kit to multiple addresses. To request a split kit, simply provide the names and addresses where each kit should be mailed in the comments section of the order form and include a note saying "please split this kit". Please note that an additional fee of $10 will apply per additional address.
Each component in the kit is labelled with barcodes that are specific to your test order. This means that even if you choose to split the kit and send the respective components to each party for sample collection, the samples will still be tested together once they arrive at the laboratory. This ensures that all samples are correctly matched to your test order, providing accurate and reliable results.
Do I need to go to a lab for DNA Sibling Testing?
No, our at-home sibling test kit allows you to collect DNA samples from the comfort of your own home. The kit includes all the necessary materials and instructions for sample collection. Once you’ve collected the samples, you simply send them back to our lab for testing.
Can a baby take the Home DNA Sibling Test?
Yes, there is no age limit for DNA testing so the test can be performed on infants as well as adults. The DNA sample is collected using a simple and painless cheek swab.
Does the Home DNA Sibling Test kit expire?
Can the DNA Sibling Test determine if the siblings have the same mother or father?
The DNA Sibling Test can provide the likelihood that alleged siblings are full siblings (sharing both parents), half siblings (sharing one parent), or not related at all. However, it cannot definitively determine which parent the siblings share. If you need to determine paternity or maternity, a DNA paternity or maternity test is recommended.
