How antibody tests help to detect those already infected with SARS-CoV-2, the virus that causes COVID-19

Published 01 May 2020

Every day, more and more people become infected with the acute respiratory syndrome coronavirus 2 (SARS-CoV-2), but only people with symptoms such as fever, cough and acute breathing difficulties may be tested. Since an infection with the virus often goes without symptoms, many people do not know that they have already been infected with SARS-CoV-2. Therefore, a high number of unreported cases is assumed. An antibody test can provide more clarity here. 

Two criteria are paramount to broad testing programmes for SARS-CoV-2: high throughput, meaning that laboratories can test a high number of samples in a short time frame, and accuracy, which means a test that provides an accurate result to the healthcare professional for diagnosis. This can be achieved by measuring antibodies against SARS-CoV-2 in blood samples.
