Antigen and Molecular Tests for COVID-19 The diagnostic testing field for COVID-19 is rapidly evolving, with many tests focused on diagnosing patients with active viral infections. Available RIDTS detect and differentiate between type influenza A and B viruses, but do not specifically identify or differentiate subtypes of influenza A viruses. The fast-spreading Omicron variant has made us increasingly reliant on at-home rapid antigen tests to tell us whether we have Covid-19. The QuickVue At-Home COVID-19 Test is a type of test called an antigen test. Understanding the false negative rates of SARS-CoV-2 RT-PCR testing is pivotal for the management of the COVID-19 pandemic and it has implications for patient management.

It can be calculated using the equation: sensitivity=number of true positives/ (number of true positives+number of false negatives). The agency said early results suggest that antigen tests "do detect the omicron variant but may have reduced sensitivity," meaning it's possible the tests could miss an infection, known as a .

Background Lateral flow devices (LFDs) are viral antigen tests for the detection of SARS-CoV-2 that produce a rapid result, are inexpensive and easy to operate. Of these, the fraction who are infected, which we can interpret as the probability that a given person who tests positive is actually one of the infected is $$ { aP \over aP + (1 - b)(N-P) } $$, We can express this formula in terms of probabilities instead of population sizes.
