Omicron globally became the predominant SARS-CoV-2 variant in late 2021. Some studies have suggested Omicron has a different replication pattern that could affect detection by rapid antigen tests. Reports in social media have promulgated oral swabs as a superior sample for detecting Omicron in the early stage of infection compared to nasal swabs.
More recently, publications report detection of Omicron by rapid antigen tests is comparable to the Delta Variant and other previous variants.
