PCR tests work by directly detecting the viral genetic material (RNA), Antigen tests work by detecting specific proteins on the surface of the virus, PCR test results can take from hours to up to one week, Antigen test results are available in less than one hour, PCR tests have a lower chance of false-negative results (a false negative means the test does not detect COVID even though the patient has it) and are more accurate, Antigen tests have a higher rate of false-negatives. The antigen test is a diagnostic test that detects the presence of a specific antigen of infectious agents, while the NAAT test is a diagnostic test that detects the nucleic acid sequence of infectious agents. Individuals tested are required to receive patient fact sheets as part of the tests Emergency Use Authorization (EUA). CDC is working with state, local, territorial, academic, and commercial partners to conduct surveillance testing to better understand COVID-19 in the United States. Required fields are marked *. Many commercial NAATs that use RT-PCR rely on multiple targets to detect the virus, such that even if a mutation impacts 1 of the targets, the other RT-PCR targets will still work.

In instances of higher pretest probability, such as high incidence of infection in the community, or a person with household or continuous contact with a person with COVID-19, clinical judgement should determine if a positive antigen result for an asymptomatic person should be followed by a laboratory-based confirmatory NAAT. The Centers for Disease Control and Prevention notes while tests are best used early in the course of illness to diagnose COVID-19, they are not authorized to evaluate the duration of infectiousness. Types of diagnostic tests currently used in the U.S. to diagnose COVID-19 virus include PCR tests (nasal swabs) and antigen tests. Because of this, it is used for the detection of highly infectious and lethal pathogens like SARS-CoV-2 that causes COVID-19. Both tests require a sample from the patient, usually a nasal swab. Some people should receive treatment. NAATs are effective because of their ability to detect very small concentrations of a virus that other tests might miss. What to know when you need a RT-PCR, Rapid PCR, Rapid Antigen, and more. 99. While many countries require PCR tests to enter, some allow for rapid antigen tests in their place, including Jamaica and Belize. PCR stands for polymerase chain reaction. This test can be performed by swabbing the back of the throat or the inside of the nose, either with a technician or with anat-home collection kit.

Understanding COVID-19 tests, including the different types of tests and their uses, and the types of samples the tests use, is key to making an informed decision that meets your needs. A negative antigen test should be repeated at least 48 hours and should be followed up with a NAAT test to confirm the results from the antigen test. And what does it mean to have antibodies? Longer turnaround time for lab-based tests (13 days), After an infection has ended, and the risk of transmission has passed, people may have detectable RNA and test positive for up to 90 days, Negative tests should be repeated per FDA guidance, Less sensitive (more false negative results) compared to NAATs, especially among asymptomatic people and with some variants. One component to move towards greater health equity is ensuring availability of resources, including access to testing for populations who have experienced longstanding, systemic health and social inequities. Even if you have a small trace of the virus in your system, the PCR test will detect it. We are the worlds largest MFG of urethane band saw tires. The key difference between antigen and NAAT test is that antigen test is a diagnostic test that detects the presence of specific antigens in infectious agents, while NAAT test is a diagnostic test that detects the nucleic acid sequence of infectious agents.
