When a Covid-19 test shows 'detected abnormal,' it indicates that the test detected the presence of the virus, but the results are not within the expected range. This could be due to various factors, such as a low viral load or a mutation in the virus that affects the test's accuracy.
COVID-19 Negative (SARS-CoV-2 RNA Not Detected) Test Result. If your COVID-19 test was negative, this means that the test did not detect the presence of COVID-19 in your nasal secretions. This result would suggest that you are not currently infected with COVID-19.
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...

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...
Negative results: With a high likelihood, the results state you were not infected with Sars-CoV-2 at the time of testing. Neither target 1 or target 2 were detected. We recommend following quarantine recommendations and universal precautions (hand washing, social distancing, and when appropriate PPE such as masks and gloves).
Dec 20, 2023 · Because intermittent detection of viral RNA can occur, a negative result on an initial NAAT followed by a positive result on a subsequent test does not necessarily mean a person has been reinfected. 11 When the results for an initial and subsequent test are positive, comparative viral sequence data from both tests are needed to distinguish betwe...
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.
