Terms of website use
The terms that apply when you use this website. They are deliberately short — if anything is unclear, contact us and we will explain.
Who we are
This website is operated by NIVHA Laboratory Services Limited, a company registered in Northern Ireland (company number NI024042). Our registered office is Unit 1B Concourse 1 Catalyst, Queens Road, Belfast BT3 9DT. Our VAT registration number is 843 4753 15. You can reach us on 02890 737942 or at info@nivha.net.
Using this website
You may browse this site and print or save pages for your own reference. The content — text, page designs and the NIVHA name and logo — belongs to NIVHA Laboratory Services Limited and may not be reproduced commercially without our written permission. Quoting short extracts with attribution is fine.
Information, not advice
The content on this site, including the information hub, is general information about drug, alcohol and DNA testing. It is not legal advice, medical advice, or advice on any individual case. Detection windows, timescales and technical figures are indicative and depend on individual circumstances. Decisions in legal proceedings should always be guided by your solicitor and by the specific laboratory report issued for your case.
Testing services are arranged separately
Nothing on this website is a contractual offer. Testing services are provided under the terms set out in the fee note or written agreement issued for each instruction, and those terms take precedence over anything on this site. Prices shown on the site are indicative and are confirmed in the fee note.
Accuracy and availability
We take care to keep the site accurate and current, but we do not guarantee that every page is free of errors or that the site will be available without interruption. We may change or remove content at any time. To the extent permitted by law, we are not liable for loss arising from reliance on the website itself — this does not limit or exclude any liability for our testing services, which is addressed in the written terms for each instruction, and nothing in these terms excludes liability that cannot be excluded by law.
Links to other sites
Where we link to external websites — for example regulators, courts or published research — we do so in good faith, but we are not responsible for their content.
Governing law
These terms are governed by the law of Northern Ireland, and the courts of Northern Ireland have jurisdiction over any dispute relating to this website.
Last updated July 2026. We may update these terms from time to time; the version on this page is the one that applies.
