Detected results are indicative of the presence of SARS-CoV-2 RNA. Due to the complexity of nucleic acid amplification methodologies, there may be a risk of false-positive results. Clinical correlation with patient history and other diagnostic information is necessary to determine patient infection status.
Apr 15, 2021 · A study of 193 symptomatic and 110 asymptomatic patients with SARS-CoV-2 infection found that viral RNA detection lasted a median of 17 to 19 days. 35 Although viral load peaks near 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...
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.
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).
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.
