Sensitivity of rapid antigen testing and RT-PCR performed on nasopharyngeal swabs versus saliva samples in COVID-19 hospitalized patients: results of a prospective comparative trial (RESTART). Test sensitivity indicates the ability of the test to correctly identify patients that have the disease. When also patients that were graded as high suspicion but never tested positive were included in the denominator, the sensitivity (95% CI) was: 67.5% (62.9-71.9%) inpatients; 34.9% (31.4-38.5%) outpatients; 47.3% (44.4-50.3%) all. These tests require samples from the patient that are likely to contain virus. Most samples are collected using nasopharyngeal swabs or a sputum cup, although the virus may also be detected in feces, urine, or blood. 2023 Mar;9:100067. doi: 10.1016/j.dscb.2023.100067. doi: 10.1002/14651858.CD013705.pub2. .

Sensitivity refers to the test's. Essentially, a lower limit of detection indicates a more sensitive test, with fewer viral copies per sample necessary to elicit a positive test result. In general, ARTs can achieve a sensitivity of about 80 per cent for cases with higher viral loads and a specificity range of 97 to 100 per cent, said HSA. There are now several studies assessing their accuracy but as yet no systematic . An official website of the United States government.
