Sibling DNA Test Kit

£149.00

The DNA Clinics Sibling Test Kit offers a simple and accurate way to determine the likelihood of a biological sibling relationship. Using non-invasive cheek swabs, results are available *next working day from receipt of samples at the laboratory. Plus, take advantage of PayPal's "Pay Later" options to spread the cost of your sibling DNA test.

This sibling DNA test uses advanced 45 DNA marker analysis, providing a higher level of confidence when assessing the likelihood of a biological sibling relationship, particularly where parental DNA is unavailable.

The standard sibling test kit includes mouth swabs for two participants. If you need to test additional individuals, please contact us at 0800 988 7107 to discuss your requirements. Additional charges will apply for each extra participant.

* Returned samples are checked to ensure everything is complete and ready for analysis. If we spot anything that could delay your results, we’ll get in touch quickly to help resolve it.

Frequently Asked Questions

How will the kit be delivered to me?

Postage is free and all single kits are delivered by Royal Mail Signed For® 1st Class.

How accurate are the sibling test results?

The sibling DNA test provides a statistical likelihood of a biological sibling relationship. By analysing 45 DNA markers, the test delivers a higher level of confidence than standard relationship testing, particularly when parental DNA samples are not available. Results are presented clearly to explain the likelihood of a full, half, or unrelated sibling relationship.

Is the DNA Clinics Test Kit suitable for legal purposes?

No, this test is intended for personal use only and cannot be used for legal purposes. If you require a legally admissible test, please contact us for further information.

Do I need parental DNA for the sibling test?

Parental DNA is not required but can improve the accuracy of the results. If possible, including the DNA of one or both parents is recommended.

Can the test be used for any age?

Yes, the test is non-invasive and suitable for individuals of all ages, including children, as it uses a simple cheek swab.

How long does it take to receive my DNA kit?

The kit will be dispatched using your selected delivery method. Faster delivery options are available at checkout.

How do I return the samples to the laboratory?

The kit includes a prepaid envelope to send your samples back to our laboratory. Simply follow the instructions provided in the kit.

Are there any additional charges?

DNA Clinics testing kits are transparent with no hidden charges. However, there are certain circumstances where additional fees may apply:

  • Swab re-collection: If the initial samples are contaminated or invalidated due to improper collection.
  • Adding participants: Fees apply for testing additional individuals beyond the standard kit.
  • Further testing: Required if initial results are inconclusive. Please see the disclaimer below for more details.
  • Legal upgrades: If you decide to upgrade to a legal test after ordering a home test kit.

For full transparency, we recommend reviewing all terms and conditions before placing your order.

What is the returns policy for DNA kits?

We want you to feel confident in your purchase of the DNA Clinics Test Kit. If you wish to return the kit, please review the following policy:

Unopened Kits:

  • You may return an unopened kit within 14 days of purchase for a full refund (except postage costs). The kit must be in its original condition, and proof of purchase is required.

Disclaimer

Due to the complexity of DNA relationship testing and the chance nature of DNA inheritance, there is a small risk of receiving an inconclusive result. An inconclusive result means that the DNA analysed does not provide sufficient evidence to establish the biological relationship being tested. The likelihood of this outcome depends on several factors, including the test participants available, individual DNA profiles and their uniqueness or commonality, and the number of genetic locations analysed.

It is important to understand and accept the risk of an inconclusive result before ordering or booking this test, as you will be required to provide consent confirming your awareness. Refunds will not be issued for inconclusive results.

We will always strive to achieve a conclusive outcome for your DNA test. If an initial test is inconclusive, additional options may be available to improve the likelihood of a conclusive result (additional fees apply). These options include:

Adding more test participants, as recommended by Crystal Health Group, to strengthen the analysis.

Conducting further analysis to compare additional loci (DNA locations).

If you are using the DNA Clinics service and booking an appointment, these options will be explained to you during the process. For those ordering a self-collection kit, we recommend calling 0800 988 7107 to discuss these options with a member of our team before placing your order.
