Do you want a DNA Siblingship Test to confirm if individuals have the same parents?

Using our simple swab based test you can determine whether two or more people are full or half siblings (sisters and/or brothers).

If the potential siblings may be related in any other way (for example they may be cousins), please call us first on 0191 233 1414 before booking your test.

It’s quick and easy to take our DNA Siblingship Test…

When you book this Peace of Mind Siblingship Test a DNA Testing Kit will be shipped in plain packaging to your address. If there are multiple addresses or you are outside of the UK additional shipping charges may apply, these will be calculated during the booking process.

The results of this test cannot be used for legal or immigration purposes. For more information and pricing details about the legal or immigration DNA Siblingship Tests we offer click here.


Who needs to take a test?

For a siblingship test, we will need a sample from each of the siblings invoved. We recommend where possible, that any available parents also participate in the test.

Please tell us the total number of people taking part in the test by selecting the appropriate drop-down box at the bottom of this page when submitting your booking.

Does the mother have to be tested?

Ideally yes, but it is possible to do a siblingship test without a sample of the mothers DNA.

If the mother is not providing a DNA sample, please tick the No box if asked as you submit the booking form.

How is the test taken?

DNA samples are taken by simply rubbing a test swab a few times on the inside of the cheek. This process collects a small sample of cells which is all we need to extract the DNA and run the Paternity Test.

A sterilised test swab for each of the people involved in the test is included in the DNA Testing Kit.

Where do we go to take the test?

You don’t need to go anywhere, you can collect the DNA samples required for the test in the privacy of your own home.

How many DNA Testing Kits do I need?

One DNA Testing Kit includes everything you need for everyone providing a DNA sample at the same address. You would only need an additional DNA Testing Kit if one or more of the people providing a DNA sample live at a different address.

What if we don't live in the same household?

If one or more of the people providing a DNA sample live at another address in the UK or in a different country we can send a DNA Testing Kit to their address as well.

If this applies to you choose the appropriate selection from the ‘Delivery instructions’ below and let us know how many people are at the second address in the ‘Test Individuals at this Address’ dropdown so we can send the appropriate number of test swabs.

If you have more than two additional shipping destinations please contact our friendly customer liaison team to arrange this.

We think we may be half siblings but may also be cousins. What test do I need?
