DNA Cousin Test

Fast, Powerful and Proven

This DNA Cousin Test is an ideal way to determine the likelihood that individuals are first cousins, when the parent(s) in question are not available for testing. The mouth swab can be collected quickly and discreetly in the privacy of your own home and sent to our laboratory for analysis.

During a DNA cousin test, a buccal (mouth) swab is taken from each alleged cousin to collect 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 using a process called PCR (polymerase chain reaction). This amplification process focuses on short tandem repeats (STRs), which are regions of DNA where a short sequence is repeated multiple times. STRs are highly variable throughout the genome, making them a reliable way to confirm or refute biological relationships.

By comparing the STR profiles of each alleged cousin, the DNA cousin test can determine the probability of a biological relationship between them.

Turnaround Time

DNA Cousin Testing is completed 3 to 5 business days after the samples arrive at the laboratory. Results are released immediately once the testing is completed.


DNA cousin testing can be arranged online, by phone or by fax. Questions can be directed to the laboratory by email at info@genetrackus.com or by phone at 1-855-284-6553. Our DNA advisors will be able to answer any questions you may have or to help you to schedule an appointment for testing.

Test Type Legal Test Kit
2 cousins $255
3 cousins $350
For legal testing, a specimen collection and witnessing charge of $50 will apply for each individual whose sample is collected at one of our locations in the U.S., and $100 for each individual whose sample is collected overseas. A $25 charge will apply if individuals in the same case are collected at different locations.


Who should consider the Private Test option?

If the alleged parent(s) in question is/are available for testing, we highly recommend the DNA Paternity Test or DNA Maternity Test over the DNA Cousin Test. If the parents of the alleged cousins are available, the DNA Sibling Test would be recommended over the DNA Cousin Test since the sibling test (although not as powerful as a parentage test) is more powerful than a cousin test. The DNA Cousin test should only be considered if absolutely no other test type can be taken as it is the least powerful of all of the available kinship tests. While the parentage tests will always provide absolutely conclusive results, the cousin test will only provide a likelihood that the individuals are first cousins versus not related at all.

Can the kit be shipped to more than one address if the parties live in different cities?

If the people being tested live at different addresses, we can divide the DNA testing kit and send each part to separate locations. The kits have barcodes to make sure the samples are still tested together when they arrive at the laboratory. To get a split kit, write “please split this kit” in the comments section of the online order form and give us the name and address of where to send each part. For example, you could say “send the Alleged Father’s part to…(provide name and address)” and “send the Child’s part to…(provide name and address).” Alternatively, you can have the complete kit shipped to you and divide it yourself, and then send the parts to the other people involved in the testing.

Who should consider the Legal Test option?

Legal DNA tests are commonly used to provide court-admissible evidence for or against biological relationships in various legal scenarios, including court cases, custody and estate disputes, and inheritance. If you choose the legal testing option, we will schedule an appointment for all parties involved to provide samples at one of our designated Genetrack chain-of-custody sample collection facilities.

What if the parties to be tested live in different cities or do not wish to attend the same appointment?

We know that it can be challenging when people involved in DNA testing live in different cities. To make things easier, we can arrange separate appointments for each person at their own location. Our scheduling department will coordinate the appointment dates for each individual, making the process as smooth and hassle-free as possible.

Is the Private Home DNA Test as accurate as the Legal Test?

The Home DNA Test is just as accurate as our standard legal tests and will provide absolutely conclusive results. The only difference between the private test and the legal test is whether the sample collection is witnessed.
