Matrix Diagnostics Workplace Drug Testing

Our aim to be at the forefront of the industry in all spheres of substance misuse detection technology has been achieved through the development of innovative onsite screening kits and the use of laboratory-based testing services. The result of that work is that Matrix Diagnostics now leads the way in effective testing for many substances, including New Psychoactive Substances (NPS), previously known as “legal highs”. The NPS detection solutions we provide are easy to use, reliable and accurate. Details of our current developments, products and services can be found in the Latest Matrix Tests section. There you will find comprehensive information about all the latest Matrix innovations including testing for NPS.

Matrix Diagnostics can supply the equipment you require to conduct onsite primary screening for the presence of drugs of several kinds. The devices require samples of oral fluid or urine, or in the case of alcohol, a sample of breath to be provided. Confirmatory testing of samples is carried out by our laboratory using mass spectrometric techniques. The chain of custody kits and the laboratory forms necessary for the submission of the samples are supplied by us. We can provide full training for staff that are to conduct screening tests and are always available to give advice or to assist in any way we can so that your drug and alcohol testing programme runs smoothly. For clients that do not wish to carry out testing themselves, we also have a 24/7 sample collection service available across the UK. Our nationwide team of collection technicians are fully trained in Chain of Custody procedures and collections in line with different Industry regulations (eg Network Rail, Nuclear, Safety Critical and many others). The guidelines set out by the European Workplace Drug Testing Society (EWDTS) state in the Laboratory Organisation section that “A Quality Management System of the organisation/laboratory is required via accreditation according to EN ISO/IEC 17025 and/or EN ISO 15189 in fields of forensic toxicology and/or workplace drug testing analysis.” Matrix Diagnostics is accredited to ISO17025 by the United Kingdom Accreditation Service (UKAS) for its in-house laboratory services.
