PCR processes are the diagnostic gold standard when it comes to identifying coronavirus infections. Unlike rapid antigen tests, they function even in the case of a low viral load and detect the pathogen with a high level of accuracy. The disadvantage of standard PCR tests is that they are not currently suited to mass, ad hoc, on-the-spot testing, where the greatest possible ease-of-use, rapid results and reasonable costs are required. Fraunhofer researchers are currently developing a scalable, open and digitalized PCR test system that will produce results in just 15 minutes. The compact demonstrator system will be on display from November 14 to 17 at the joint Fraunhofer booth (Hall 8a, Booth G10) at the COMPAMED trade show in Dusseldorf.
