At Cansford Labs, we specialise in fast, accurate drug and alcohol testing, delivering reliable results with UK’s fastest turnaround times from our lab in Cardiff.

We’ve been at the forefront of hair testing in the UK for over 30 years. Our founders helped pioneer the process, and our team has spent every year since improving the science and widening access to dependable, high-quality testing. Today, we offer a growing range of services including segmented hair analysis, nail testing, PEth and DNA testing, with an ever-expanding list of substances.

We don't just give a yes or no answer. Every result we produce is quantifiable and transparent. A Certificate of Analysis comes as standard with each test, and when more detail is needed, our scientists can provide clear, expert reports that include formal declarations, sample detail and their qualifications. All of this is delivered within three working days of receiving the sample.

Our nationwide network of over 50 trained collectors can reach any location in the UK within 48 hours, making it easy to get testing started quickly, wherever you are. We’re proud to work with anyone who needs accurate, science-backed results they can trust.

Whether you're supporting a family, managing risk, or making decisions that rely on clear evidence, we’re here to help with a knowledgeable, approachable team that’s with you at every step.
