Important Information


Siblings are brothers and/or sisters. Full-siblings have the same mother and father, while half-siblings share only one parent. A sibling test can be used to confirm whether two, or more children are related and to identify if they share one or both biological parents.

Sibling analysis is not as conclusive as paternity testing and can only report the most likely relationship ‘given the DNA evidence’.

The results will provide a statistical likelihood of whether two individuals are true biological relatives but DNA testing for this type of relationship cannot provide a conclusive result. Because of the patterns of DNA inheritance it is not always possible to detect a half sibling relationship or to differentiate between a half or full sibling and so it may not always reveal the true nature of the relationship, or provide strong evidence.

However, this type of DNA analysis is the best way to investigate a sibling relationship and if either of the parents of the siblings are available for testing, this will aid the analysis and may increase the certainty of the result.

Please note that DNA@Home's sibling test is for ‘curiosity’ purposes only; if the results are going to be used in a legal matter they may not be accepted by the UK courts and we would encourage you to visit our legal DNA testing site to order a test - www.cellmark.co.uk.

As with all our DNA relationship testing services we offer a Next Day DNA service at no extra cost.  This means that if all the DNA samples for your test arrive at our UK laboratory before 10am, we aim to send the test result to you by the end of the next working day by email (also please see our FAQs).

DNA relationship testing can be a life changing event and we would urge that before ordering a test you think carefully about the potential outcomes.
