Testing for COVID-19 During the Age of Omicron (JCM ed.)
Listen now
In less than two months since it was discovered, the omicron variant of SARS-CoV-2 has become the dominant variant of the virus, causing an unprecedented rise in the number of cases of COVID-19 in the U.S. and elsewhere. The emergence of this variant has quickly led to some surprising claims about diagnostic testing for omicron and a renewed appreciation of the importance of sequencing the viral genome for typing purposes. We will address several questions about testing for omicron, including: • Are rapid antigen tests sensitive for detection of omicron? And should people swab their throats to increase the sensitivity of these tests? • How does the emergence of omicron change our use of polymerase chain reaction tests for SARS-CoV-2? • How can we definitively identify the omicron variant and do we have the needed capacity for this?

The applications of large multiplex panels for detection of pathogens have greatly expanded in the past several years. Initial tests were for detection of respiratory viruses, and the first such test was labor intensive and vulnerable to frequent contamination. Since then, additional sample types...
