SARS-CoV-2-Diagnostik – was ist wirklich sinnvoll?

The PCR-test for SARS-CoV-2 represents the state of the art in diagnosing COVID-19 disease as at November 2020. However, above all this is time-consuming. In future, so-called antigen tests could be carried out quickly and as a point-of-care method to facilitate the diagnosis of COVID-19. Changes in serological biomarkers (such as D-dimers, troponin T, CRP) can help to identify patients at risk for a severe COVID-19 course. A routine screening CT thorax to identify COVID-19 pneumonia is currently not recommended by most radiological societies. However, the number of CT examinations is increasing steadily and radiological diagnosis in COVID-19 patients with pulmonary symptoms is becoming more and more important.
