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.
Details. LOINC®. Back to Top. 2019 Novel Coronavirus (COVID-19), NAA. TEST: 139900. CPT: 87635. Print Share Include LOINC® in print. Synonyms. 2019 Novel Coronavirus. COVID-19. SARS-CoV-2. Special Instructions. Please note: Labcorp does not currently collect specimens for this test.
May 12, 2023 · Amplifying those nucleic acids enables NAATs to detect very small amounts of SARS-CoV-2 RNA in a specimen, making these tests highly sensitive for diagnosing COVID-19. In other words, NAATs can reliably detect small amounts of SARS-CoV-2 and are unlikely to return a false-negative result of SARS-CoV-2.

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 · For diagnosing current SARS-CoV-2 infection, the CDC recommends using a specimen from the upper respiratory tract (e.g., nasal, nasopharyngeal). 5 Testing lower respiratory tract specimens is also an option in certain circumstances (e.g., in those receiving mechanical ventilation).
Apr 15, 2021 · SARS-CoV-2 is the novel coronavirus that causes COVID-19. The spectrum of asymptomatic, presymptomatic, and symptomatic SARS-CoV-2 transmission presents challenges for evaluating...
Types of molecular tests being developed for SARS-CoV-2. Current antigen and molecular tests with FDA EUA Status. What is needed to perform a molecular test? Molecular tests require samples—such as nasopharyngeal surface cells or sputum/saliva—that are likely to contain the virus.
