About Our DNA Tests

To provide for the wide variety of needs of our customers, we offer a wide range of DNA testing services designed to give the answers you are looking for. Our home DNA test kits, and variety of other DNA testing services, will provide the results you need to move on with your life. We carry out thorough quality checks on each of the three phases of our DNA testing procedure to make sure you receive the most trustworthy and accurate DNA test results: case login, DNA analysis and generation of the DNA test report. This rigorous supervision of our procedures is just part of the reason why so many choose GTL for a reliable paternity test, D.N.A. testing or genetic testing.

Most DNA tests or paternity tests cause a host of strong emotions including stress, anticipation and excitement. We realise that this is more than enough to be coping with and that the last anything a customer needs is additional anxiety caused by taking a DNA test that requires a lot of time or money. Our home DNA testing kit allows you the option of collecting DNA samples in the privacy or your own home before sending them to our DNA laboratory for analysis. Once your D.N.A. test is complete, your results report will be available for download from our website. DNA test results can be telephoned, emailed or posted for an additional administration fee, currently £5 for telephone, £10 for email and £15 for first class post.

DNA Sample Collection

DNA tests are extremely sensitive and it is therefore very important that the DNA samples are collected carefully and in accordance with our instructions to avoid cross-contamination.

You may choose from two different methods of collecting DNA samples: Buccal Mouth Swab and Blood sample.

  • The most common and popular method of DNA sample collection is by using buccal mouth swabs to swab the inside of the cheek of each participant. This is a quick, reliable and painless method

  • A DNA blood test uses a small blood sample that can either be taken by a doctor or by piercing the finger with a small lancet. A small drop of blood is then transferred to a collection card. If you are considering the blood sample option please contact your doctor or health professional to discuss the collection of samples for children younger than 8-years-old.

Please continue to read for additional information about our informational, or Peace of Mind, DNA tests and legal paternity tests as the sample collection procedures are different in each case.

Informational (Peace of Mind) vs. Legal DNA Test

There are many reasons why families order DNA tests. Whether you are seeking to determine paternity, maternity, siblingship or any other family relationship, we are here to help. However, before you order a DNA testing kit, it is very important that you think about whether you need the test for your own informational purposes, or for legal reasons.

If you are looking for your own peace of mind and the DNA test results will be for personal use only then our informational tests are appropriate.

If the test results are to be used in court, for the Child Support Agency, General Register Office or a visa application then we highly recommend that you choose our legal DNA test option.

Both types of test are carried out with the same attention to details and using the same technology but the legal DNA testing option requires additional procedures to be followed. These requirements include: completion of relevant application forms with signatures of consent, participation of an unrelated third party, positive photographic identification and return of sealed samples by Recorded Delivery, Special Delivery or courier.
