Need Results for Legal Proceedings?
Standard at-home Cousin Test kits generally cannot be used for court proceedings or other official purposes. For court-admissible results accepted by US courts and government agencies (e.g., USCIS), choose our Legal DNA Cousin Test.
How is a Legal DNA Cousin Test different?
Legal DNA tests follow a strict chain-of-custody process that private, at-home kits cannot provide:
- Verification of government-issued photo ID
- Submission of passport-style photos
- Fingerprinting at the time of sample collection
- Witnessed specimen collection by an impartial third-party witness.

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.

Establish First Cousin Relationships with Confidence.
DNA Tests Direct is committed to providing accurate, private, and reliable DNA testing services. Here’s what sets our cousin DNA test apart:
- Accredited Laboratory: Our testing laboratory holds major international accreditations, including AABB, CAP, and CLIA, ensuring your test is performed to the highest international standards.
- Fast and Secure Results: Receive your confidential results through our secure online portal in just 1-2 business days from when our lab receives your samples.
- Comprehensive Analysis: Our laboratory analyzes up to 27 genetic markers to deliver the most accurate statistical assessment of your potential cousin relationship.
- Dual-Process Testing: Every test undergoes our dual-process analysis, meaning your samples are independently tested twice to ensure maximum accuracy.
Understanding Your DNA Cousin Test Results
The DNA Cousin Test analyzes genetic markers to establish the statistical likelihood that two individuals share a biological first cousin relationship. This test produces a Combined Kinship Index that indicates the probability of a biological relationship:
- A value greater than 1.0 suggests a biological cousin relationship is more likely than not.
- A value less than 1.0 suggests a biological cousin relationship is unlikely.
- The further the index is from 1.0 (either much higher or much lower), the stronger the evidence for or against a cousin relationship.
For example, an index of 100 means it’s 100 times more likely these individuals are biological first cousins than unrelated individuals with similar genetic backgrounds.

Frequently Asked Questions
What is a DNA Cousin Test and when would I need one?
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.
How accurate is the DNA Cousin Test?
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.
Can the DNA Cousin Test kit be shipped to multiple addresses?
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.
Can these results be used for legal purposes?
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.
Does the DNA test kit expire?
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.
How do I read my DNA Cousin Test results?
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.
Is the collection process difficult?
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.
Can the DNA Cousin Test determine distant cousin relationships?
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.
