Conclusively determine twin zygosity.
This at-home DNA twin test kit provides a definitive determination of zygosity through convenient, simple mouth swab samples. With this easy-to-use home kit, you can collect a mouth swab quickly and discreetly in the privacy of your own home and send it to our laboratory for analysis. Your test results will be available for download from your secure online account within 1-2 business days of receipt at the lab.
The test conclusively establishes whether twins are identical or fraternal. Identical twins share 100% identical DNA profiles, while fraternal twins average 50% shared genetic material like ordinary siblings. This test also applies to higher-order multiples such as triplets or quadruplets.
DNA Twin Test Methods
During a DNA Twin Test, a buccal (mouth) swab sample is collected from each twin. The sample contains cells, and most of the cells in our body contain a full set of genetic information in the form of DNA (deoxyribonucleic acid). A person’s DNA represents a “genetic blueprint” and, like a fingerprint, it is unique to each individual.
At the laboratory, the DNA is extracted from the cell and specific regions of the DNA are amplified by a process known as PCR (polymerase chain reaction). Our test analyzes 16 to 27 of these specific regions, called short tandem repeats (STRs). STRs are regions of DNA in which a short DNA sequence is repeated multiple times. They are found throughout the genome and are highly variable, providing an accurate way to confirm or refute biological relationships.

Frequently Asked Questions
Can you ship the DNA Twin Test kit to multiple addresses?
Absolutely. If the individuals participating in the test are in different locations, we can send parts of the DNA test kit to different cities. During checkout, please enter “Please split kit” in the “Additional Notes” comments box and let us know where to send each component. For example, you can say “Send one kit to [Name, Address]” and “Send the second kit to [Name, Address]”. Each component is individually barcoded, ensuring that your samples will be tested together once they arrive at the laboratory.
Can I use these results for legal purposes?
If you need DNA results for legal purposes, such as court proceedings, child custody or support, or inheritance claims, you will need to order the Legal DNA Twin Test. Legal DNA Twin Tests require a chain of custody procedure to be admissible in court. This involves having the DNA samples collected by a neutral third party, proper identification of the test participants, and the samples being directly sent to the testing laboratory. Legal DNA Twin Testing is available in the US, Canada and UK.
Is there an age limit for DNA twin tests?
No, there are no age restrictions for participating in a DNA twin test. This test is suitable for individuals of any age, including newborns. For minors, a legal guardian’s consent is required.
Does the DNA test kit expire?
No. The test kits do not have an expiration date and can be stored indefinitely before sample collection. However, once a sample is collected, it’s best to return the kit to our laboratory for testing within 3 months.
How is the DNA sample collected?
DNA collection is a simple, safe, and painless process. It involves gently rubbing a brush (buccal swab) inside the mouth against the cheek for 15 seconds.
How do I read my DNA Twin Test results?
Your results will show two numbers (alleles) that indicate the number of repeats that you received from each parent at each STR. You may have two identical alleles at a marker, or you may have two different alleles. These allele numbers are compared between the individuals to conclusively determine whether the twins are identical twins or fraternal twins.
