What is a DNA Cousin Test?

A DNA cousin test is a scientific method used to determine whether two individuals are biologically related as cousins. The test compares parts of each person’s DNA to see if they share a significant amount of genetic material. Because cousins share a portion of DNA inherited from common ancestors (such as grandparents), analysing these genetic markers can provide strong evidence of a biological relationship.

How Does a DNA Cousin Test Work?

DNA cousin tests are highly accurate for establishing the likelihood of a biological relationship. However, because cousins share less DNA than parent-child pairs, results are typically presented as a probability rather than a definitive yes or no. Due to this there is a chance for an 1 in 2 chance inconclusive results. Including a parent sample to the testing process (mother or father), will improve the results and increase the chance of achieving a conclusive result. The test fees are inclusive of up to 4 parties. Our laboratory uses advanced techniques to provide the most reliable results possible.

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.
