COVID-19 Antibody testing
In response to the COVID-19 pandemic, we have launched our first COVID-19 serology test – also called an antibody test – which determines whether an individual has previously been infected with SARS-CoV-2, even if they were asymptomatic.
The first test, which has been CE marked and fully approved, and carefully validated against community-based COVID-19 cases, is available now. There will be further variations of this test to come. Below we summarise some of the science and performance properties of our test and the ways in which it has been validated.
