Twin Test

Private Knowledge DNA Twin Test

Starting at $150

The DNA Twin Zygosity test will conclusively determine whether twins are fraternal twins or identical twins. After ordering this test, a buccal swab collection kit will be sent to you. Follow the instructions provided in the kit to collect a fast and simple mouth swab sample from each twin using the swabs provided in the kit. The sample collection process is simple and painless and takes only a few seconds to complete. After sample collection, return the sample to the laboratory for testing using the return package included in the kit. Once the laboratory receives your samples, testing begins immediately and the results are available within 3 to 5 business days. The full genetic report and results document will be sent to you by mail and email.

What if the Twins live in different cities?

If the twins live in different addresses, the kit can be split and sent separately to each address. To request a split kit, please write "Split kit please" in the comments box of the order form. Please also indicate the name and shipping address for each individual's portion of the kit.

How does the DNA Twin test work?

The DNA Twin test examines the Autosomal STR markers in the twins. Identical twins have exactly the same genetic material and will have exactly the same Autosomal STR profile once the test is completed. Fraternal twins are the same as regular siblings and will not have exactly the same DNA. Fraternal twins will have different Autosomal STR profiles. The results of the Twin Zygosity test will conclusively and clearly state whether the twins are identical or fraternal twins.

Is there an age limit?

No, the sample can be collected from individuals at any age, even newborns.

Is there a time limit for using the kit?

The unused kit will remain stable indefinitely at room temperature so you can use it at any time after you receive it. Once you open the kit and collect the samples, the sample will remain stable for at least 3 months after sample collection.

How long does the test take and how will I receive the results?

The turnaround time for testing is 3 to 5 business days after your samples arrive. At the time that you place the order, you can choose to receive your results by email, mail or both. If you had chosen email as the method for receiving your results, your results will be sent to you by email the same day that testing is completed.
