Sibling DNA Tests

There are three types of Sibling DNA Test, depending on family make-up.

Full Sibling vs Half Sibling - the test is designed to establish if two individuals share both parents or just one parent.
Half Sibling vs Unrelated - the test is designed to establish if two individuals share one parent in common.
Full Sibling vs Unrelated - the test is designed to establish if two individuals share both parents in common or no parents in common.

Once you place your order DNA Worldwide will work with you to establish the exact details. For instance with a Full Sibling vs Half Sibling Test, if it is known that two individuals share the same mother but they are unsure if they share the same father then it is important to advise DNA Worldwide.

The Ordering Process

To start the process either order online or over the phone (01373 800130). DNA Worldwide will send you a simple to use DNA collection kit. If participants are located in different parts of the UK or World then DNA Worldwide can send a kit direct to each participant (please call to provide the details).

Once the samples are received your DNA Testing case manager will contact you to establish the exact type of sibling relationship to be tested.

Unique Testing Method: The DNA Worldwide Sibling DNA Test is the most advanced in the world testing up to 46 DNA Markers.
Conclusive Range: We aim to achieve a 99.99% Yes or 100% No but this is not always possible and depends on how unique the participants' DNA is and who can be tested. Results may show down to 80% yes or 15% No.
Turnaround Time: 5-10 Business Days
Participants: Two alleged full- or half-siblings and any parent is optional, but strongly suggested. The probabilities can be increased greatly if other known relatives are available for testing.

Procedure: DNA samples are collected from two alleged (full or half) siblings at home or at a DNA collection centre (any parent is optional, but strongly suggested).

The samples are obtained using a cheek swab (provided by DNA Worldwide). After samples are sent to the laboratory, results will be available within 5-10 Business Days.

Customer Story

"When I was 15, my Father showed me a photograph of a boy and told me it was given to him by the boy's mother who implied that he was my father's son! The instant I saw it I knew that this boy was my brother. I waited until I was an adult to make my search. Ten years later, I finally found my little brother. But I had to get my family as well as my father to accept him. I came across DNA Worldwide, got my father and new brother to perform the quick, easy procedure, and two weeks later, I could finally prove to the world what I already knew."
