What Is GTL DNA (gtldna.co.uk) and What DNA Testing Services Does It Offer?

Updated

GTL DNA, at gtldna.co.uk, is the website of Genetic Testing Laboratories, a UK-based DNA testing service provider. It offers home and legal paternity tests, prenatal paternity testing, relationship tests, animal DNA tests, and health, wellbeing and ancestry tests. Its home paternity test (alleged father, mother and child) starts at £89, with results issued in 3–5 working days, and testing is described as covering 21 loci in an ISO 17025-accredited laboratory.

Who runs the site and what does it claim?

The site presents Genetic Testing Laboratories as an experienced UK DNA testing provider. The main claims it makes about its service are:

  • 21 loci tested — the number of genetic markers analysed in its tests.
  • ISO 17025 accreditation — the laboratory standard it says underpins its results.
  • 3–5 working days for standard results, with an express option for paternity and maternity tests that returns results in 3 working days from the moment samples reach the laboratory, for a small additional fee.
  • No hidden fees on the home paternity test starting at £89.

These are the provider's own statements. If accreditation matters for your use case — for example, a legal test — check the specific accreditation and chain-of-custody arrangements with the company before ordering.

What tests does GTL DNA offer?

The service list is broad. It falls into several groups:

Category Tests listed
Paternity Home paternity testing, legal paternity testing, immigration DNA testing
Prenatal Non-invasive prenatal paternity test, baby gender test
Relationship Sibling, twins, grandparent, aunt/uncle, MtDNA, Y chromosome, genetic reconstruction
Animal Dog DNA, dog parentage, dog disease, dog intolerance, dog allergy, feline PKD, horse DNA/parentage/profile, avian sexing
Health & wellbeing Diet and healthy weight, skin care, lactose intolerance, celiac disease genetic test, genetic predisposition
Ancestry Ancient DNA hub, GPS Origins ancestry test, paternal lineage, maternal lineage
Other Hair drug test, DNA profile testing, disaster victim identification, surrogacy DNA testing

A few practical distinctions matter when choosing:

  • Home vs legal testing. Home tests are for personal information. Legal tests follow a different sample-collection process so results can be used for official purposes. The site treats these as separate services, so pick the one that matches your intended use.
  • Standard vs express. The faster 3-working-day turnaround applies to paternity and maternity tests and costs extra; the clock starts when samples arrive at the laboratory, not when you order.
  • Prenatal testing. The non-invasive prenatal paternity test is listed separately from the baby gender test. Both are prenatal services but answer different questions.

How do you order and what happens next?

The site provides an Order Now entry point and a Request Callback option, plus a phone number (01273 748926) and an offices/contact section. A Payment Options page sits under Resources.

The general flow implied by the site is:

  1. Choose the test that matches your question (home vs legal, paternity vs relationship, etc.).
  2. Order online or request a callback to discuss your case.
  3. Collect and send samples using the site's sample collection procedure guidance.
  4. Receive results in the stated turnaround once samples reach the laboratory.

Before ordering, confirm two things with the company: whether your chosen test is the home or legal version, and whether the express option applies to it. The site's Frequent Questions, Sample Collection Procedure and Home vs. Legal DNA Testing pages are the places to check those details.

Is it worth considering?

GTL DNA is a reasonable starting point if you want a UK-based provider with a published price (£89 for a home paternity test), a stated accreditation (ISO 17025) and a short turnaround (3–5 working days). It is less suited to situations where you need certainty about legal admissibility without first confirming the legal-test process, or where you want a consultation before committing — in those cases, use the callback option or contact the office directly rather than ordering from the price headline alone.
