Micropathology Ltd was created in 1995 to provide a coherent and organised rapid molecular diagnostic service for infectious disease in the United Kingdom Hospital sector, initially serving the population by supplying a bespoke service to the National Health Service and Health Protection Agencies laboratories. A small amount of work was also supplied to some private diagnostic laboratories. This service has grown steadily since that time, supported by constant in-house research and development which monitors and further enhances the company’s activity and also responds to requests from clinical colleagues. Project work for collaborative research with university and clinical departments, and dovetailing this to the core activity, is undertaken on a selected basis. The staff at Micropathology are of Postdoctoral level and have many years of service with this company creating a hierarchy of combined experience over 17 years, concentrating on infectious disease and genetic studies. They have unrivalled development experience in creating bespoke diagnostic assays and sequencing organisms for further study and identification. The major public genetic databases are reviewed regularly for each organism for which there is a diagnostic assay so that information on genetic variants ensures that the diagnostic work is always up to date with the current genetic knowledge. The company staff also contribute to worldwide genetic databases. The reputation of the company has allowed a steady recruitment of very highest calibre staff to add and constantly refresh the pool of expertise.
