Diagnostics for SARS-CoV-2

The improvement of diagnostic tools not only enables better and faster identification of infected persons, but can also advance the detection of cleared infections with potential immunity to SARS-CoV-2.

Sniffing for a corona diagnosis

A research team led by the Foundation of the University of Veterinary Medicine Hannover (TiHo), in cooperation with the German Federal Armed Forces, the Hannover Medical School and the University Medical Center Hamburg-Eppendorf, published a study on dogs that can sniff out people infected with the SARS-CoV-2 virus in the specialist magazine BMC Infectious Diseases. The dogs only needed to be trained for one week to differentiate between samples from SARS-CoV-2 infected patients and non-infected controls. The method could be used in public areas such as airports, at sporting events, at borders or other mass events as a supplement to laboratory testing to prevent further spread of the virus or outbreaks.

Going beyond clinical routine in SARS-CoV-2 antibody testing

A multiplex corona virus test for the evaluation of cross-reactivity to endemic coronavirus antigens

Given the importance of the humoral immune response to SARS-CoV-2 as a global benchmark for immunity, a detailed analysis is needed to monitor seroconversion in the general population, under¬stand manifestation and progression of COVID-19 disease, and ultimately predict the outcome of vaccine development. In contrast to currently available serological assays, which are only able to resolve the SARS-CoV-2 antibody response on an individual antigen level, we developed a multiplexed immunoassay, for which we included Spike and nucleocapsid proteins of SARS-CoV-2 and the endemic human coronaviruses in an expanded antigen panel. Compared to three commercial in vitro diagnostic tests, our MultiCoV-Ab achieved the highest sensitivity and specificity when analyzing a well-characterized sample set of SARS-CoV-2 infected and uninfected individuals. Simultaneously, high IgG responses against endemic coronaviruses became apparent throughout all samples, but no consistent cross-reactive IgG response patterns could be defined. In summary, we have established and validated, a robust, high-content-enabled, and antigen-saving multiplex assay MultiCoV-Ab, which is highly suited to monitor vaccination studies and will facilitate epidemiologic screenings for the humoral immunity toward pandemic as well as endemic coronaviruses.
MultiCoV-Ab will be used in a series of national and international epidemiological studies.

Mathematical decision-making aids for more efficient COVID 19 tests

An interdisciplinary team of mathematicians, computer scientists and physicians from Die Junge Akademie, the Technical University Braunschweig, the University Stuttgart and the company Arctoris has developed a decision support tool that calculates which method in a positive sample pool identifies all persons suffering from COVID-19 as effectively as possible. Using so-called pooling methods, samples from different people can be combined into a pool and tested for COVID-19 in a test kit.
