At-Home Sibling DNA Test
A sibling DNA test helps determine whether two individuals share one or both biological parents. It’s especially useful when the alleged father or mother is unavailable for direct testing. There are two types of sibling tests:
Half-sibling test — checks if two people share one biological parent
Full-sibling test — checks if they share both biological parents
The test uses a simple mouth swab to collect DNA from each sibling. Including the mother’s DNA (if available) can improve the accuracy of the results.
- Free and discreet first class delivery via Royal Mail
- Simple cheek swab collection
- Fully accredited UKAS laboratory
- Results usually within 1 working day from receipt of your samples
Half Sibling : Test to prove the donors share one parent
Full Sibling : Test to prove the donors share both parents

What our customers say
Frequently asked questions
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 Sibling 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 Sibling 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.
What’s included in an At-Home Sibling DNA Test kit?
Each AssureDNA kit includes self-sampling swab packs, full instructions, a pre-paid return envelope, consent documents, and access to support. Kits are sent in discreet packaging for privacy and results are emailed securely once testing is complete.
What does a sibling DNA test prove?
A sibling DNA test determines whether two people share one or both biological parents. AssureDNA offers full and half-sibling tests, ideal for confirming family connections when a parent is unavailable for testing.
How accurate are half-sibling DNA tests?
Half-sibling DNA tests are highly accurate when processed by an accredited laboratory like AssureDNA. Accuracy improves when a parent of one or both siblings is also tested. Our 25 DNA ‘marker’ analysis ensures a clear determination of sibling relationships.
Can you DNA test half-siblings?
Yes, you can test for a half-sibling relationship using our at-home Half Sibling DNA Test. This test determines whether two people share one biological parent. It's a simple cheek swab analysed in our accredited UK laboratory for fast, precise results.
How accurate is a half-sibling DNA test without a parent?
While a half-sibling DNA test is still possible without a parent’ sample, including one can improve the test's accuracy. Without a known parent, the probability of a conclusive result can be lower, as it becomes more difficult to determine which genetic markers were inherited from which side. Should an inconclusive result be returned, we can offer additional testing or the inclusion of another relative’s sample to assist with resolution of the case.
