Sample Size and Duration of Study: The aim is to test 100 unique patients. There are $N - P$ who are not infected, and of these the tests of $b(N-P)$ will return negative. Sensitivity was dependent upon the CT value for each sampling method. The x-axis corresponds to number of days after first reported symptoms, with 0 indicating 1 day before symptoms onset. The overall sensitivity of rapid antigen detection tests versus that of RT-PCR with oral, anterior nasal, and nasopharyngeal samples was 18.18% (95% confidence interval [CI] 8.19% to 32.71%), 63.04% (95% CI 47.55% to 76.79%), and 73.33% (95% CI 58.06% to 85.4%), respectively. These rapid tests detect basic levels of antigen already present in a sample, providing only a simple yes or no, similar to a pregnancy test.

The terms sensitivity and specificity may not appear in the manufacturers information sheets, but are often reported as positive percent agreement and negative percent agreement. Sensitivity may also be measured by calculating the limit of detection, which is the lowest detectable number of virus copies in a sample at which the test will return a positive result at least 95% of the time. Noninclusion in this list should not be interpreted as a judgment on the validity or legitimacy of tests. May 27;58(8):938.

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 viral genomic material for SARS-CoV-2 is ribonucleic acid (RNA), which remains in the body only while the virus is still replicating, even at very low levels. Rapid antigen detection tests using self-collected anterior nasal swabs proved to be as sensitive as and more tolerable than professionally collected nasopharyngeal swabs for CT values up to 30 determined by RT-PCR. A test's sensitivity portrays how many positive cases are detected out of total pool of positive cases. The clinical sensitivity of SARS-CoV-2 RT-PCR testing was only moderate at best.
