DNA Cousin Test

Discover the likelihood of a biological first cousin relationship with our reliable DNA Cousin Test. Get fast, accurate results delivered discreetly online within just 1-2 business days after samples reach our accredited laboratory. This test is ideal when exploring family connections, though we recommend a paternity test for more definitive results when the potential father is available for testing.

At-Home DNA Testing

DNA Cousin Testing

Explore your family connections with the DNA Tests Direct At-Home DNA Cousin Test. This premium DNA test calculates the statistical likelihood of whether two individuals are biological first cousins, helping you discover meaningful connections within your extended family. Enjoy the convenience and privacy of at-home testing with our simple-to-use mouth swab collection kit.

Important Note: The DNA Cousin Test provides probability-based results rather than definitive answers. We recommend choosing our paternity, sibling, or grandparent tests whenever possible, as these provide stronger statistical evidence. This test is specifically designed for first cousin relationship assessment and cannot reliably determine more distant biological connections.

Frequently Asked Questions

A DNA Cousin Test determines the statistical likelihood that two individuals are biological first cousins by comparing their genetic markers. This test is particularly useful for individuals researching family histories, exploring genealogical connections, or when trying to establish biological relationships in cases of adoption, separation, or unknown parentage. The test is ideal when more direct relationship testing (parents, siblings) isn’t possible due to unavailability of those individuals.

Our DNA Cousin Test provides a statistical likelihood rather than a definitive answer. The test analyzes up to 27 genetic markers and delivers a Combined Kinship Index showing how likely a cousin relationship is compared to no relationship. Because first cousins share approximately 12.5% of their DNA, results are less definitive than parent-child testing but still provide valuable evidence. For strongest results, we recommend testing with our paternity or sibling tests whenever possible.

If participants live in different cities or countries, we can split the DNA test kit and ship components to separate addresses. Each kit part is individually barcoded for secure tracking, and testing begins once all samples have arrived at our laboratory.

To request a split kit, include the following in the “Additional Information” section at checkout:

“Please send Person A’s kit to [Name, Address] and Person B’s kit to [Name, Address].”

Note: Additional shipping fees apply for multi-address orders.

For legal matters such as court proceedings, inheritance claims, or immigration, you will need to order the Legal DNA Test. This test requires a chain of custody procedure to ensure the results are admissible in court. The process includes having DNA samples collected by an impartial third party, proper identification of participants, and samples being directly sent to the testing laboratory.

No, the kit has no expiration date and can be stored indefinitely before collecting your sample. However, once the sample is collected, we recommend returning it to the lab within three months for optimal testing.

Your test report is designed to be easy to understand. The most important part of your result is the “Combined Kinship Index,” which is a single number that summarizes all the genetic evidence. As a general guide, a Kinship Index value greater than 1.0 indicates that a biological first cousin relationship is likely. The higher the value is above 1.0, the stronger the probability. A value less than 1.0 indicates that the relationship is unlikely.

The collection process is simple and painless. Your kit includes easy-to-use cheek swabs that you gently rub against the inside of the cheek for about 30 seconds. This collects more than enough DNA for testing without any blood or needles. The process works for everyone, including infants. Your kit includes clear instructions, and our customer service team is available if you need assistance.

Our DNA Cousin Test is specifically designed to assess first cousin relationships and cannot reliably determine more distant biological connections like second or third cousins. First cousins share about 12.5% of their DNA, which is enough for meaningful statistical analysis, but more distant relationships have significantly less shared DNA, making reliable assessment difficult. For exploring more distant family connections, we recommend genetic genealogy services that analyze much larger portions of DNA.
