The Randox COVID-19 test underwent evaluation within, and was accepted by, Public Health England.

In its evaluation of the Randox COVID-19 test, Public Health England’s report noted that the assay correctly identified all positive and negative samples without exception.

Randox have almost 40 years of experience as a primary manufacturer in the IVD (in vitro diagnostics) industry. Last year we manufactured over 3 billion tests and exported to 145 countries. Randox are an ISO 13485 accredited manufacturer of in-vitro diagnostic medical devices, are a provider of a global laboratory accreditation scheme (RIQAS) accredited to ISO 17043, and run a number of ISO 17025 accredited laboratories. As an exporter to 145 countries and a manufacturer to other diagnostic companies we undergo multiple external audits each year, in order to remain engaged with our global markets.

At the time of the emergence of the COVID-19 threat, Randox had already developed seven CE marked assays for a range of viruses, including a number of other coronaviruses.

Upon identifying the latest strain of coronavirus as a significant global threat, Randox was able to harness our R&D capability, and some 40 years’ in diagnostics, including viral tests, to develop an effective COVID-19 assay with the same rigorous validation processes that we applied to all our other assays.
