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 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.

The test may be useful as a sensitive indicator of trauma induced by brain injury to laboratory rats. [7] Alcohol markedly impairs mouse performance in the rotarod test. [8] Research using the rotarod test with various chemical agonists and antagonists may help scientists determine which components of neurons mediate the effects of chemicals. [9]
Because of this it is better to do the open field test in conjunction with other tests such as the elevated plus maze and light-dark box test. [13] Different results can be obtained depending on the strain of the animal. [4] Different equipment and grid lines may cause different results. [14]
A NASA illustration of a lateral flow assay. A lateral flow test (LFT), [1] is an assay also known as a lateral flow immunochromatographic test (ICT), or rapid test.It is a simple device intended to detect the presence of a target substance in a liquid sample without the need for specialized and costly equipment.
In 2000, the Federal Research Division, Library of Congress, published the results of an analysis of its Rats/Mice/and Birds Database: Researchers, Breeders, Transporters, and Exhibitors. Over 2,000 research organizations are listed in the database, of which approximately 500 were researched and of these, 100 were contacted directly by FRD staff.
However, there is some debate between scientists whether increased immobility instead demonstrates learning or habituation, and would therefore be a positive behavioural adaptation: [8] the animal is less fearful because it is now familiar with the environment of the test. This interpretation is supported by the fact that even rats who are ...
