Discover Your Sibling Relationship with Our Home DNA Sibling Test Kit
Curious about your sibling relationship? Our at-home DNA sibling test kit provides reliable results to determine if you’re full-siblings, half-siblings, brothers, or sisters. Conveniently collect DNA samples with our painless mouth swabs in the privacy of your own home. All tests are conducted in an accredited laboratory to ensure the highest standards of accuracy and reliability.
A Reliable Alternative
When testing the alleged father is not possible, our DNA test for siblings offers a reliable alternative. While a paternity test the most conclusive results for establishing biological fatherhood, our sibling test uses statistical analysis to assess the likelihood of a full-sibling or half-sibling relationship, providing valuable insights when a paternity test is not available.
Fast, Simple, and Painless
Say goodbye to long waiting times and complicated procedures. Our DNA sibling test kit is designed for speed and simplicity. In just 1 to 2 business days, you’ll receive discreet online results, providing you with the answers you need without the wait. Skip the clinic visits and complex sample collection methods. Our easy-to-use DNA kit allows you to perform the test easily at home.
Easy to Use
Enjoy the convenience of free nationwide shipping. Your sibling DNA test kit will be delivered to your doorstep in a discreet, unmarked package, with detailed instructions that guide you through the process step by step. Simply follow these instructions to collect painless mouth swab DNA samples.
Once you’ve collected the samples, use the prepaid return envelope included in the kit to send them back to our lab. Within just 1-2 business days after your samples arrive at the laboratory, you’ll receive confidential results through a secure online portal.
Comprehensive Testing
Our DNA test analyzes up to 27 STR loci, providing precise and comprehensive results. Whether you’re full-siblings, half-siblings, brothers, or sisters, our sibling DNA test helps you understand the genetic likelihood of your biological connection. Each test is performed twice in a AABB, CAP, CLIA and ISO 17025 accredited laboratory, providing increased accuracy and reliability.
Confidential and Secure Results
We understand the importance of privacy when it comes to your personal genetic information. That’s why we ensure all testing and results are kept strictly confidential. Your results will be available through a secure online portal, allowing you to access and review them whenever it’s convenient for you.
Simple and Convenient Mouth Swabs
Our DNA testing process uses painless mouth swab sample collection kits suitable for all ages.

Fast Testing Turnaround: 1 to 2 Business Days
Collection Method: Painless Mouth Swabs
Tested Individuals: DNA test kit for 2 alleged siblings
Number of Markers Tested: Up to 27 STR Loci
Age Limits: None – this test can be performed at any age
Laboratory Accreditations: AABB, CAP, CLIA, ISO17025
Reliable Core CODIS Markers
Our DNA sibling test focuses on the core loci recognized by CODIS, which are highly reliable markers in forensic DNA analysis. These markers meet stringent CODIS standards, ensuring accurate and trustworthy results.
Legal Sibling Test Option Available
If you need DNA sibling test results that are legally admissible, we offer a legal DNA test option. Our private sibling test is just as accurate as the legal test, with the only difference being the sample collection process. With the private test, you can discreetly collect the samples at home. In contrast, the legal test requires collection at a designated site in the presence of a third-party witness. Both tests provide the same reliable results, with the only distinction being whether the collection is witnessed or done privately. Schedule a legal DNA sibling test by clicking here.
Everything you need is included in the kit – no lab fees!
Our DNA sibling test kit provides you with everything you need to collect a painless mouth swab DNA sample and send it to our laboratory for testing. Once you’ve collected the sample, simply return it to our laboratory using the pre-paid shipping label provided in the kit. We take care of all laboratory fees, ensuring there are no additional costs or surprises.

Can the sibling test kit be shipped to multiple addresses?
If the test participants live in different locations, we offer the option to split the DNA test kit and send the components to different addresses. Simply provide the mailing addresses and names of the test participants under the Additional Information section during checkout. Please note that an additional shipping fee of $10 will apply for each additional address within the United States. Our laboratory will process the samples upon arrival, and each kit component is individually barcoded for accurate tracking.
How conclusive are DNA sibling tests?
It’s important to note that DNA sibling tests are not as powerful as DNA paternity testing. While our DNA paternity test provides an absolutely conclusive result regarding paternity, a DNA sibling test offers a statistical analysis of the probability of a sibling relationship. If testing the alleged father using a DNA paternity test is possible, it is recommended as the most conclusive and powerful test. However, in situations where testing the alleged father is not possible, a DNA sibling test can provide valuable insights into the statistical likelihood of a full or half-sibling relationship.
What will my DNA sibling test tell me?
The sibling test results are determined through a statistical analysis based on the expected genetic similarities observed in true full and half sibling pairs. During the analysis, the autosomal STR profiles of the alleged siblings are to generate a Combined Kinship Index value. This value represents the probability of a sibling relationship, taking into account the statistical expectations for genetic matches among siblings.
Here is a general interpretation of the Combined Kinship Index values:
Combined Kinship Index >10000 = Practically proven
Combined Kinship Index from >1000 to 10000 = Highly likely
Combined Kinship Index from >100 to 1000 = Very likely
Combined Kinship Index from >10 to 100 = Likely
Combined Kinship Index from >1 to 10 = Slightly more likely than unlikely
Combined Kinship Index of 1 = Inconclusive
Combined Kinship Index from 0.1 to <1 >Can I use the results from the home sibling test kit in court?
No, the home sibling test is for personal knowledge only. It is not suitable for legal purposes that require strict adherence to the chain of custody. If you need test results that can be used as legal evidence, we highly recommend choosing the legal DNA test. The legal DNA test ensures that samples are properly documented, handled, and stored to maintain their integrity and admissibility in a court of law. Sample collection for the legal test must take place at a designated location with an impartial third-party witness present. Click here to schedule a legal sibling DNA test.
How can the power of the DNA sibling test be increased?
The DNA sibling test is not as powerful as the DNA paternity test. The power of the DNA sibling test can be increased by adding the mother to the test or by adding more siblings.
Can a paternity test be done between siblings?
In cases where the alleged father cannot be tested and the question is whether 2 siblings who share the same mother also share the same father, a DNA sibling test can provide the likelihood that sibling pairs are full siblings (same mother and father) or half siblings (only one parent in common).
How does the sibling DNA test work?
The DNA sibling test compares the STR profile of siblings to generate a full sibling index and a half sibling index. Theses indexes provide the likelihood that two individuals are full or half siblings. It will also provide the likelihood that they are not related at all.
I need to bring this kit out of the country. How soon do I need to collect the sample?
The DNA sibling test kit does not have an expiration date, so you can purchase it in advance and take it at any time. After the samples are collected, the DNA is good for at least 3 months at room temperature so you have lots of time in the event that you cannot send it back right away for testing. Just remember to follow the instructions in the kit to ensure that you collect the samples correctly.
