In testing pathogens, the collected sample is used to extract genetic material (DNA or RNA). Some tests may be able to be performed frequently because they are less expensive and easier to use than other tests, and supplies are readily available. Nucleic acid amplification test (NAAT) is a method in molecular biology that amplifies genetic material using several ways such as polymerase chain reaction, strand displacement amplification, or transcription-mediated amplification. Her research interests include Bio-fertilizers, Plant-Microbe Interactions, Molecular Microbiology, Soil Fungi, and Fungal Ecology. Then, the next step of the NAAT amplifies the genetic material by making many copies of it for detection. 2. Terms of Use and Privacy Policy: Legal. All rights reserved.

Plus, the test will only pick up if the virus is active in your body, meaning asymptomatic cases when someone doesnt have any symptoms are harder to identify with the antigen test. Results from NAATs are considered the definitive result when there is a discrepancy between the antigen and NAAT test. NAAT is a method in molecular biology that amplifies genetic material using several methods, while PCR is a method in molecular biology that amplifies genetic material using only thermal cycling. The other class of test is an antibody test, also known as a serological test, which tests for the presence of antibodies associated with COVID-19 in your blood.

They may represent increased resistance or even immunity to the virus; however, antibody tests are not used to detect active infection. Therefore, the results are produced very fast in the diagnostic context. For more information, see CDCs COVID-19 isolationguidance.

As new tests are authorized for use, they are added to these tables so that anyone can access up-to-date information on all authorized tests and collection kits. WebA NAT looks for the actual virus in the blood. However, the amounts of DNA generated in many NAT tests are very small. The message is clear: Get tested, as its one of our best defenses against stopping the spread of COVID-19. Public health surveillance testing is intended to monitor population-level burden of disease, or to characterize the incidence and prevalence of disease. The rapid test cant detect small amounts of the virus or asymptomatic cases as accurately as the PCR test can, Heather said. It also requires minimal training or infrastructure. This test looks for the virus' RNA in a patient's sample. Rather, these tests, also known as serology tests, look for antibodies that may have formed in a patient's blood due to a previous infection, according to the CDC.
