quickvue covid test sensitivity and specificity

While PCR-tests are usually considered as the gold standard to detect infection with the SARS-CoV-2 coronavirus in terms of sensitivity as well as specificity, antigen tests (Ag-Tests) offer practical advantages in terms of costs, logistics and speed [].Because Ag-Tests may play a major role in large scale testing strategies [2, 3] in populations with low prevalence, besides . Specificity is compounded It may be helpful to define some terms here. ShelfLife : At least 9 months from date of manufacture. Download the complete list of laboratory-developed tests (xlsx). 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 the 370 COVID-19 diagnostic tests that the US Food and Drug Administration has authorized for emergency use in the US, there are dozens you can take at home. A systematic review of the sensitivity and specificity of lateral flow 2021 Feb 9;11(2):e047110. Quidel Corporation Headquarters: This site is relatively easily accessed, compared to the final site of viral infection: the lower respiratory tract. There was no statistically valid correlation between the semi-quantitative PCR result and the QuickVue result. Included in the complete list are sensitivity and specificity measures, specimens required, target genes, and test details. While the main advantage of rapid antigen detection tests is the immediate availability of results, PCR should be preferred in crucial settings wherever possible. Sensitivity measures how often a test correctly generates a positive result for the condition being tested. Overall test sensitivity was 84.9% (95% CI 79.1-89.4) and specificity was 99.5% (95% CI 98.7-99.8). Before Effectiveness of isolation, testing, contact tracing and physical distancing on reducing transmission of SARS-CoV-2 in different settings. *Testing is limited to laboratories certified under the Clinical Laboratory Improvement Amendments of 1988 (CLIA), 42 U.S.C. Nasal swab is a good alternative sample for detecting SARS-CoV-2 with rapid antigen test: A meta-analysis. QuickVue SARS Antigen Test. 2021;23(4):407416. However, the reliability of the tests depends largely on the test performance and the respective sampling method. . Specificity, on the other hand, measures a test's ability to correctly generate a negative result for people who do not have the condition being tested . dba MicroGen DX, Orig3n 2019 Novel Coronavirus (COVID-19) Test, UNC Health SARS-CoV-2 real-time RT-PCR test, University of North Carolina Medical Center, Infectious Disease Diagnostics Laboratory within the Department of Pathology and Laboratory Medicine at the Childrens Hospital of Philadelphia, Yale New Haven Hospital, Clinical Virology Laboratory, 96.1% (SARS-CoV-2), 95.5% (flu A), 91.7% (flu B), 100% (SARS-CoV-2), 99% (flu A), 96.8% (flu B), NAAT (reverse transcriptase isothermal amplification), Real time TMA, Dual Kinetic Assay (DKA), multiplex, 96.1% (SARS-CoV-2), 100% (flu A), 100% (flu B), 99.6% (SARS-CoV-2), 99.2% (flu A), 100% (flu B), molecular isothermal Reverse Transcriptase Helicase-Dependent Amplification (RT-HDA), isothermal amplification, Home collection, 96.2% (SARS-CoV-2), 100% (flu A), 98.3% (flu B), 100% (SARS-CoV-2), 98.9% (flu A), 100% (flu B), transcription-mediated nucleic acid amplification (TMA), Antigen Paramagnetic Microbead-based Immunoassay, non-isothermal nucleic acid amplification (qSTAR), Isothermal amplification (OMEGA), patented, 98.4% (symptomatic), 99.1% (asymptomatic), GetMyDNA COVID-19 Test Home Collection Kit, 95.2% (symptomatic), 95.4% (asymptomatic), 97.7% (symptomatic), 97.5% (asymptomatic), 96.4% (SARS-CoV-2), 100% (influenza A), 100% (influenza B), 98% (SARS-CoV-2), 99.6% (influenza A), 99.7% (influenza B), 100% (automated extraction), 96.7% (manual), 93.3% (automated extraction), 93% (manual), transcription mediated amplification (TMA), Cedars-Sinai Medical Center, Department of Pathology and Laboratory Medicine, Pathology/Laboratory Medicine Lab of Baptist Hospital, Miami, Florida.

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. For antibody tests, it is the ability to identify samples where no SARS-CoV-2 antibodies are present. 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. CDC: While government employees, students and the general public had to wait in line for hours in the beginning of the pandemic, at-home test kits make it easy to diagnose for the novel coronavirus in less than 30 minutes. Testing among symptomatic participants indicated the following for the BinaxNOW antigen test (with real-time RT-PCR as the standard): sensitivity, 64.2%; specificity, 100%; PPV, 100%; and NPV, 91.2% ( Table 2 ); among asymptomatic persons, sensitivity was 35.8%; specificity, 99.8%; PPV, 91.7%; and NPV, 96.9%.
