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 ...

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.2There may be a window period of up to 5 days after exposure before...
Antigen-based diagnostic tests are widely used at home, at the point of care, and in the laboratory because of their low cost, rapid turnaround time, and availability. Antigen tests and laboratory-based NAATs have similar high specificity. False positive test results can occur with antigen tests, although they are unlikely when the tests are used c...
NAATs, such as reverse transcription polymerase chain reaction–based diagnostic tests, which detect viral nucleic acids,7are the most sensitive tests for detecting current SARS-CoV-2 infection. Diagnostically, some NAATs may produce false negative results if a mutation occurs in the part of the virus’s genome that is assessed by that test.8 The FDA...
Unlike NAATs and antigen tests, which detect the presence of SARS-CoV-2, serologic or antibody tests can detect recent or prior SARS-CoV-2 infection or vaccination. The CDC recommends that antibody tests should not be used to diagnose current SARS-CoV-2 infection.12 It may take 21 days or longer after symptom onset for seroconversion to occur (i.e....
Currently, antibody tests are not recommended for assessing SARS-CoV-2 immunity following COVID-19 vaccination or for assessing the need for vaccination in a person who is unvaccinated. The FDA has issued EUAs for more than 80 SARS-CoV-2 serologic tests since the beginning of the pandemic. However, these tests are not currently authorized for routi...

Apr 15, 2021 · The incubation period, or time from exposure to symptoms, for COVID-19 ranges from two to 14 days, with a median of 5.1 days (97.5% of patients with the disease become symptomatic by 11.5...
Jan 9, 2024 · Nucleic acid amplification tests (NAATs) are highly sensitive and highly specific tests that detect one or more viral ribonucleic acid (RNA) genes. PCR tests are the most common type of NAAT used for COVID-19 testing. Viral RNA may stay in a person’s body for up to 90 days after they test positive.
