COVID-19 rapid antigen tests (RATs) have been widely used for diagnosis of COVID-19. The World Health Organization (WHO) COVID-19 Case Definition states that a person with a positive RAT (also known as an antigen rapid diagnostic test or Antigen-RDT) can be considered a "confirmed case of SARS-CoV-2 infection" in two ways.

A COVID-19 Rapid Antigen test(top) with a Covid-19 Rapid Antigen and a Influenza A&B Rapid Antigen Test(bottom) A rapid antigen test (RAT), sometimes called a rapid antigen detection test (RADT), antigen rapid test (ART), or loosely just a rapid test, is a rapid diagnostic test suitable for point-of-care testing that directly detects the presence or absence of an antigen.

COVID-19 rapid testing in Rwanda. An antigen is the part of a pathogen that elicits an immune response. Antigen tests look for antigen proteins from the viral
NBC News medical fellow Dr. Akshay Syal breaks the down the differences between the rapid and PCR Covid tests, as well as how they fair against the omicron variant.
When a positive rapid antigen test goes from a dark line to a very faint line, this means that the virus load in the swab is probably less than when then line was dark, he adds.
False negative tests can occur and the general expectation for antigen tests is an 80% accurate detection rate for infection, says David Cennimo, M.D., infectious disease expert and associate ...
Antigen tests can be analyzed within a few minutes. Antigen tests are less accurate than PCR tests. It has a low false positive rate, but a higher false negative rate. A negative test result may require confirmation with a PCR test. [8] Advocates claim that antigen tests are less expensive and can be scaled up more rapidly than PCR tests. [8]
As rapid antigen COVID-19 tests measure the presence of viral proteins, even a faint line positive result indicates that SARS-CoV-2 has had an impact on your immune system.
