Covid-19 tests are designed to detect the presence of the SARS-CoV-2 virus, which causes Covid-19. These tests can be performed using different methods, including polymerase chain reaction (PCR) tests and antigen tests. The results of these tests can be categorized as either 'detected' or 'not detected.'. When a test shows 'detected,' it means ...
COVID-19 Positive (SARS-CoV-2 RNA Detected) Test Result. If your COVID-19 test was positive, this means that the test did detect the presence of COVID-19 in your nasal secretions. This result would suggest that you are currently infected with COVID-19. If you had a positive COVID-19 test, please self-isolate at home as much as possible ...
The Coronavirus SARS-CoV-2 (COVID-19) by nucleic acid amplification test is for in vitro diagnostic use under the FDA Emergency Use Authorization (EUA) for U.S. laboratories certified under CLIA to perform high complexity tests. This test has not been FDA cleared or approved. In compliance with this authorization, please visit https://www ...
Apr 15, 2021 · Molecular and antigen tests can detect current SARS-CoV-2 infection and are used to diagnose COVID-19. Clinicians should consider a test's characteristics, test timing in relation to symptom onset ...

Point-in-time screening testingSerial screening testingWhen screening testingis used, it should be applied to participants regardless of vaccination status. Any type of viral testcan be used for screening purposes; however, consider the characteristics (including accessibility, accuracy and efficiency) of different test types to determine which best suits screening testing needs. People without symptom...
Settings that should be prioritized for screening testinginclude facilities and situations where transmission risk is high and the population served is at high risk of severe outcomes from COVID-19 or there is limited access to healthcare, including: 1. Specific settings that have demonstrated high potential for rapid and widespread virus spread to...
Dec 20, 2023 · Diagnostic Testing for SARS-CoV-2 Infection. For diagnosing current SARS-CoV-2 infection, the Centers for Disease Control and Prevention (CDC) recommends using either a nucleic acid amplification test (NAAT) or an antigen test. 1 Testing may also be used for screening and to determine the length of a patient’s isolation period. 2 There may be a window period of up to 5 days after exposure ...
May 12, 2023 · Updates as of June 16, 2021. Clarified the differences between laboratory-based and point-of-care NAATs. A Nucleic Acid Amplification Test, or NAAT, is a type of viral diagnostic test for SARS-CoV-2, the virus that causes COVID-19. NAATs detect genetic material (nucleic acids). NAATs for SARS-CoV-2 specifically identify the RNA (ribonucleic ...
