About
Our Sibling DNA Test can determine if individuals are full or half siblings.
Full siblings share both biological parents, whereas half siblings share only one parent—either mother or father.
To conduct a sibling DNA test, we use cheek swabs to collect DNA samples from each individual. For the most accurate results, we recommend including a DNA sample from the biological mother if possible.
Upon receiving the samples, our expert geneticists analyze and compare the DNA to establish genetic profiles and calculate a sibling DNA index or likelihood ratio.
- A likelihood ratio above 10 indicates a strong probability that the individuals are either full or half siblings.
- A likelihood ratio below 0.1 suggests the individuals are unlikely to be related.
- A likelihood ratio between 0.1 and 10 is inconclusive, meaning the relationship cannot be definitively determined based on the statistical analysis.

What is a DNA Sibling Test?
A DNA sibling test is a scientific method used to determine whether two individuals are biologically related as siblings. This test compares specific regions of DNA from both individuals to evaluate the extent of genetic overlap. Full siblings typically share about 50% of their DNA, while half-siblings share about 25%. The test results can confirm whether the tested individuals share one or both parents, helping to clarify their biological relationship.
How accurate are DNA tests?
A DNA test is the most accurate way to determine paternity or a familial relationship, and the vast majority of our tests give a conclusive result first time. If the results are not conclusive we will contact you to discuss additional testing options. Our laboratory also offers other types of relationship testing, just contact us using the below details for more information.
Are results confidential?
Yes, under the requirements of UK Data Protection laws, all services and results are confidential. Everyone who gives a sample or has Parental Responsibility for the child in the case is entitled to request a copy of the results.
Who can consent for a child under 16 years old?
If the child is under 16 years old, consent is required from a person with parental responsibility for that child.
A mother automatically has parental responsibility for their child, and can provide consent. A father normally has parental responsibility for a child if they are named on the birth certificate, or were married to the child’s mother when the child was born. A more detailed explanation of who has parental responsibility for a child can be found here. Copies of documents to prove parental responsibility and ID must be provided. Please make sure the signature on your ID matches your signature on the consent form.
What consent is required for children (16+ years old)
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 the 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.
As with other biological sample procedures, consent is required before a sample of blood, saliva or hair is taken for analysis. Under the Human Tissue Act 2004 consent is also required (in England, Wales and Northern Ireland) for the use and storage of a sample to obtain scientific or medical information about an individual which relates to another person; this includes paternity testing. 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.
What is informed consent?
The person giving consent must understand what they are consenting to – the type of test and what it will show. It is also important that they have given serious consideration to the implications of finding out the results of the Test – the consequences of which may be irrevocable.
Consent must be voluntary, i.e. the person giving consent must give consent of their own free will and must not be subjected to undue influence, pressure or threat of any kind.
Consent may be withdrawn at any time. If any party to a test subsequently withdraws their consent, Assure DNA must be notified immediately and the processing of samples will be stopped.
In Scotland, a person who is 16 or over has the legal capacity to consent for themselves.
