Matrix Diagnostics

Matrix Diagnostics Ltd is a UK-based specialist testing laboratory providing comprehensive drug, alcohol, and blood-borne virus (BBV) screening services for workplaces and healthcare providers. Part of the Medigold Health Group since 2022, the company is positioned as a leading diagnostics provider focused on helping businesses protect their employees and reduce the operational, safety, and legal risks associated with substance misuse. Its core mission is to support organisations in creating safer, healthier work environments through accurate, fast, and legally defensible testing combined with a full suite of supporting services.

The laboratory offers an end-to-end service that extends well beyond sample analysis. Alongside laboratory testing, Matrix Diagnostics supplies on-site and back-to-lab screening products, provides 24/7 testing availability, and delivers complementary services including workplace drug and alcohol policy reviews, staff and manager training, and ongoing customer support. This holistic model allows employers to build and maintain a complete substance-screening programme — from policy design and point-of-care testing through to confirmatory laboratory analysis and expert interpretation.

Matrix Diagnostics processes a range of sample types using validated, accredited methods. Urine and oral fluid samples are analysed in-house with results typically reported within 24 hours of receipt, while hair testing is carried out in partnership with a trusted specialist laboratory, with results available within 72 hours. The testing workflow combines immunoassay screening with confirmatory liquid chromatography tandem mass spectrometry (LC-MS/MS), the gold-standard technique for confirmation toxicology. Test kits are supplied with full chain-of-custody documentation, ensuring that results are robust and legally defensible — an essential requirement for safety-critical industries and any case that may be subject to challenge or litigation.

The laboratory's analytical scope covers a broad panel of drugs of abuse and their metabolites. Detectable compounds include amphetamine, methamphetamine, cannabinoids (THC), cocaine, opiates, 6-MAM (a heroin marker), methadone, buprenorphine, benzodiazepines, fentanyl, ketamine, phencyclidine (PCP), propoxyphene, methcathinone, mephedrone (MCAT), and the prescription medicines gabapentin and pregabalin. Hair testing extends the menu further to include alcohol biomarkers such as ethyl glucuronide (EtG) and fatty acid ethyl esters (FAEE), new psychoactive substances, and anabolic steroid panels — providing a longer detection window suitable for retrospective and abstinence-monitoring programmes.

Quality and accreditation are central to the laboratory's credibility. The Matrix Diagnostics laboratory holds UKAS accreditation to ISO/IEC 17025:2017 (accreditation number 8771), with a scope covering oral fluid and urine testing, demonstrating technical competence and the validity of its methods. The wider organisation is also certified to ISO 9001:2015 for quality management and ISO 14001:2015 for environmental management through Alcumus ISOQAR. In addition, the company is registered with RISQS (the Railway Industry Supplier Qualification Scheme), reflecting its work in safety-critical rail testing, and holds Cyber Essentials certification endorsed by the National Cyber Security Centre (NCSC), underscoring its commitment to data security across its digital reporting systems.

The industries and sectors served by Matrix Diagnostics span any environment where workplace safety, regulatory compliance, and substance misuse policy are priorities. These include rail and transport, construction, manufacturing, logistics, energy and utilities, and the healthcare sector, as well as occupational health providers who integrate testing into broader employee wellbeing programmes. The emphasis on legally defensible, chain-of-custody testing makes the laboratory particularly well suited to safety-critical and disciplinary applications where results must withstand scrutiny.

To support its clients operationally, Matrix Diagnostics provides digital tools and human expertise in tandem. The M-Lab online portal allows customers to monitor test progress, order supplies, and manage their account, while a secure results portal (results.matrixdiagnostics.co.uk) delivers reports efficiently. Telephone support from experienced laboratory scientists and a network of field-based testing specialists ensures that clients receive guidance on test selection, result interpretation, and programme management throughout their engagement.

With UKAS-accredited methods, mass spectrometry confirmation capability, rapid turnaround times, a comprehensive analyte menu across multiple sample matrices, and the backing of the Medigold Health Group, Matrix Diagnostics is a credible and well-established partner for organisations seeking reliable workplace drug, alcohol, and BBV screening. Its combination of accredited laboratory science, chain-of-custody integrity, and wraparound advisory services makes it a strong choice for buyers requiring dependable occupational and forensic toxicology testing in the UK.
