IBDNA: DNA Tests, Prices and Legal Options in England

International Biosciences, better known as IBDNA, is an independent DNA testing provider offering family relationship tests, pet DNA services and selected genetic health screening. Based in the United Kingdom and supported by an international network of offices, the company presents itself as a practical option for both local and cross-border cases. This guide explains what IBDNA offers, how its testing process works, and what you need to know if you want results that may be used within an official framework in England and Wales.

What is IBDNA?

IBDNA is the trading name of International Biosciences, a UK-based DNA testing company that offers services for paternity, maternity, siblingship, grandparentage, avuncular testing, pet DNA analysis and genetic predisposition screening. One of its practical strengths is its international reach: the company states that it can coordinate testing worldwide, which is especially useful when participants live in different countries.

Why do people choose IBDNA?

Several points stand out in IBDNA’s positioning.

First, the company emphasises accuracy and quality control. According to its FAQ, DNA tests are run twice and double-checked as part of its quality assurance process. Second, it places strong emphasis on confidentiality, with discreet packaging, password-protected files and controlled access to results. Third, it offers both private tests for personal information and legal-format tests for cases where formal identification and supervised sample collection are required.

Family DNA tests offered by IBDNA

IBDNA offers a broad range of family relationship tests for people who want to confirm or exclude a biological link.

The best-known option is the home paternity test, which starts from £89 and is presented as a private, non-court procedure. The maternity DNA test is also listed from £89, while the sibling DNA test starts from £149 and the grandparent DNA test from £149. For cases involving aunts or uncles, IBDNA also offers an avuncular DNA test, which is useful when the alleged parent cannot be tested directly.

For readers who want to better understand how a private kit differs from a court-admissible procedure, our guide to a private paternity test without legal procedure is a useful starting point. If the question concerns the maternal line rather than the alleged father, our article on maternity DNA testing explains which test format is usually the most relevant. And when the direct parent is unavailable, a sibling DNA test may help clarify the probability of a biological relationship.

Legal DNA testing in England and Wales

This is one of the most important distinctions to understand. A private DNA test and a legal DNA test do not serve the same purpose.

A private test is designed for personal information only. By contrast, a legal DNA test requires identity verification, supervised sample collection and formal chain-of-custody procedures. On its legal testing pages, IBDNA states that court-approved requests are handled through a partner laboratory accredited for parentage testing directed by the civil courts in England and Wales. This matches the official GOV.UK guidance on court DNA tests, which states that a test intended for court use must be carried out by an accredited laboratory.

In practical terms, this means that anyone who may need to use DNA results in a dispute over parentage, family proceedings or another official context in England should avoid ordering a simple home kit by default. The correct format is a legal DNA test, not a standard private one.

Dog DNA tests: what does IBDNA currently offer?

IBDNA also markets several canine DNA services. Its breed-identification offer is presented from £69, with results typically available in about three weeks after the laboratory receives the sample. The company also lists dog parentage, inherited disease and intolerance-related services in its animal testing category.

There is, however, one detail worth clarifying. The older dog allergy test page is still online, but it currently states that the test is not available and redirects attention to a dog intolerance test instead. That distinction matters, because many pet owners use the words “allergy” and “intolerance” interchangeably even though laboratories may market them as separate products.

Genetic predisposition testing: useful, but not a diagnosis

IBDNA also offers a Genetic Predisposition Test priced at £195, with a stated turnaround time of 4 to 5 weeks. According to the company, this screening covers 34 diseases and traits and includes areas such as cancers, cardiovascular or cerebrovascular conditions, diabetes and obesity.

This type of test should be understood carefully. IBDNA itself states that the report is provided for informational and educational purposes, and that it does not replace medical advice. The company also recommends consulting a doctor or genetic counsellor for interpretation. In addition, it notes specific limitations, including incomplete coverage for some conditions such as hereditary breast and ovarian cancer risk, and the fact that some calculations are based on European population data. In other words, this is better seen as a risk-orientation tool than as a clinical diagnosis.

Is IBDNA a good option?

For users looking for a UK-facing DNA provider with international reach, IBDNA offers a fairly broad service range. Its strengths are clear: strong emphasis on confidentiality, a wide choice of family relationship tests, legal-format options for England and Wales, and a broader catalogue that also includes dog DNA services and genetic predisposition screening.

Its main point of attention is not reliability, but choosing the right test format. A private test may be sufficient for personal reassurance, but it will not automatically meet court requirements. Likewise, a health predisposition screen can provide useful indications, but it should not be confused with a full diagnostic genetic work-up. When the purpose is clear from the outset, IBDNA can be a practical and credible choice for private, legal or international DNA testing.
