  • Secure online results in 1-2 business days.
  • Painless, non-invasive & suitable for all ages.


The DNA Family Check Cousin Test offers a fast and reliable way to determine the likelihood of a first cousin relationship between two individuals. Our simple and painless mouth swab process allows individuals of any age, from infants to adults, to easily collect DNA samples at home.

Once you’ve collected your samples, simply return them to our accredited laboratory using the prepaid return shipping label. Our laboratory follows rigorous quality standards and conducts each DNA test twice for absolute accuracy.

Your results will be available online within a secure portal, allowing you to access them immediately after testing is complete. With a processing time of just 1-2 business days, you don’t have to wait long to receive the answers you’re looking for.

The DNA Family Check Cousin Test is best suited for situations when the alleged parent and other close relatives are deceased or otherwise unable to participate in DNA testing. If the parent in question is available for testing, the paternity test or maternity test is highly recommended as it can provide 99.999%+ definitive answers about biological relationships, compared to the statistical likelihood from a cousin test.

How it works




The DNA Family Check Cousin Test is a simple and convenient way to determine the likelihood of two individuals being true first cousins. With painless mouth swab sample collection and quick results in 1-2 business days, you can have peace of mind in the privacy of your home. Our accredited laboratory ensures double testing for absolute accuracy. Order your test today and discover your biological connection.

The DNA Family Check Cousin Test is a reliable method of investigating first cousin relationships. However, unlike paternity or maternity tests, cousin tests provide a statistical likelihood rather than a definitive answer. The results are provided as a “combined kinship index” indicating the likelihood of the tested individuals being related as cousins.

Once the samples arrive at our state-of-the-art laboratory, your results will be ready in just 1-2 business days. You can easily keep track of your test status within your secure online portal, and we’ll notify you the moment your results are available.

A kinship index is a value that indicates the likelihood of a biological relationship between two individuals. If the kinship index result is less than 1.00, this indicates non-relatedness. If the kinship index is greater than 1.00, this indicates that the two tested individuals are more likely to be true biological relatives. The higher the value of the kinship index, the stronger the likelihood that the two individuals are true biological relatives.

While the Home Cousin DNA Test provides valuable information, particularly in cases where the alleged parent is unavailable, it’s important to understand that it’s not as definitive as a paternity or maternity test. The Cousin DNA Test offers a probability or likelihood of a biological relationship, rather than a conclusive result. It is a valuable tool when direct parentage tests are not feasible, helping to piece together family relationships.

Yes. We respect your privacy and handle all information and samples with utmost confidentiality. All test kits ship out discreetly in an unmarked package. Your results are only accessible to you via secure online access, and we do not share or sell your data to any third party.

Yes, we can accommodate testing individuals who live in different cities or countries by splitting the kit and sending each component to the specified locations. When your sample kits arrive at the lab, our lab will match the samples using the unique identification numbers provided in each kit. To arrange a split kit, include the full names and mailing addresses of each person in the comments box of the online order form or contact our customer support team.

While our home Cousin Test provides the same accurate results compared to our legal tests, it is not admissible for legal purposes as it is not a chain-of-custody test. Legal testing requires sampling to be done and witnessed by a third-party impartial collector, and all participants must provide identification at the time of the appointment.

“My ex-girlfriend contacted me to say that I may be the father of her 5 year old daughter. Your test proved that I am the true biological father. It’s a life changer. Thank you.”

Jared, SD

“I was very impressed with the ease and discretion of the testing process. I received my results quickly and quietly.”


“My husband has always mentioned that our two children maybe did not belong to him and accused me of being involved with his friend at the time that our children were conceived. I knew that this was not true. We finally decided to get a paternity test done to put an end to this. Sure enough, the results of the paternity test indicated greater than 99.9999% that he was the father of our children. Our family is now closer than ever before.”

R. Stern, Seattle, WA
