A cousin DNA test helps establish whether two individuals are first cousins, which implies a shared grandparent. It is most often used when direct relatives (like parents or grandparents) are not available for testing.
DNA samples are collected using cheek swabs from both individuals. While cousin tests are less conclusive than paternity or sibling tests, they can still provide strong statistical support for or against a biological relationship—especially when other known relatives (e.g., a parent) are included.
Results are calculated using 24-marker DNA comparison, with a likelihood ratio that indicates the probability of a cousin-level relationship.

Non-invasive DNA tests — how do they work?
A non-invasive DNA test uses a simple cheek swab to collect DNA without needles or clinic visits. At AssureDNA, our sample collection kits are easy to use at home and returned to us to be analysed in our UKAS-accredited laboratory for accurate, confidential results.
What consent is required for an At-Home Cousin DNA Test?
No test will be undertaken without the consent of each adult to be tested (unless a court has ruled otherwise). Each adult is required to sign a Consent Form. An adult is someone who is 18 years or over. A child of 16 or 17 years of age is presumed to be capable of giving consent and may give consent as if they were an adult. Each participant over the age of 16 years will need to consent for their DNA to be tested and will need to support this with a suitable copy of identification.
How long does it take to get DNA test results?
At AssureDNA, we deliver results the next working day after your samples arrive at our laboratory. With fast kit dispatch, first-class Royal Mail delivery, and efficient processing, you’ll have your answers quickly.
Are the results confidential?
Yes, under the requirements of UK Data Protection laws, all services and results are confidential. Only those conducting a test or those consenting for people in the test can see the report.
Are At-Home Cousin DNA Test legally admissible in court?
AssureDNA offers tests for peace of mind purposes. Legal tests require strict chain-of-custody protocols. If you're looking for a legal test (for example, to use in Court), just get in touch and we can guide you through our legal testing service.
