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. Settings that involve close quarters and that are isolated from healthcare resources (e.g., fishing vessels, wildland firefighter camps, or offshore oil platforms). Antibody testing does not diagnose current infection. Additionally, while the CDC requires all international travelers to get a test within three days of boarding a flight to the U.S., rapid viral tests are acceptable. 2. Types of diagnostic tests currently used in the U.S. to diagnose COVID-19 virus include PCR tests (nasal swabs) and antigen tests. Furthermore, antigen tests are typically less specific and less sensitive than NAAT tests. For additional information on reading and understanding your test results, see Understanding At-Home OTC COVID-19 Antigen Diagnostic Test Results.

If someone had exposure to another person with COVID-19, but the exposed individual has had COVID-19 within the past 30-90 days,* consider using antigen tests (rather than an NAAT, such as a PCR test) to identify a new infection. The test allows for self-collection* and elution of a nasal swab sample, minimizing the potential for transmission between subject and tester. Please see FDA guidanceon the use of at-home COVID-19 antigen tests. Polybelt can make any length Urethane Tire in 0.095" or 0.125" Thick. If a person has received one or more COVID-19 vaccinations, it does not affect the results of their SARS-CoV-2 diagnostic or screening tests (nucleic acid amplification tests [NAAT], antigen or other diagnostic tests). Similarly, Croatia allows visitors to present proof of having recovered from the virus in place of a COVID-19 test. Antigen tests, the other major type of coronavirus test, while much faster, are less accurate. These are at-home or point-of-care tests that provide results typically within about 15 minutes, according to the CDC. Therefore, test results of an antigen test should be confirmed with a highly sensitive PCR test. To help frontline workers identify people infected with COVID-19, Abbott launched it's lab-based molecular tests, which are used on our m 2000 RealTi m e system (available in hospitals and molecular labs around the world) and our new Alinity m system.
