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.

[2] In the U.S., the numbers of rats and mice used are not reported, but estimates range from around 11 million [ 3 ] to approximately 100 million. [ 4 ] 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.
The test can detect antipsychotic-like activity both in the case of dopamine D 2 receptor antagonists and in the case of drugs lacking D 2 receptor antagonism. [1] [2] [6] The occupancy of the D 2 receptor by antagonists of this receptor required to inhibit the CAR is around 65 to 80%, which is similar to the occupancy at which therapeutic antipsychotic effects occur in humans with these drugs.
This is a list of rodents of Australia. [1] [2] Australia has a large number of indigenous rodents, all from the family Muridae.The "Old endemics" group are member of tribe Hydromyini, which reached Australasia between 11 – 9 million years ago from Asia, while the "New endemics", members of the tribe Rattini, are presumed to have arrived more recently, between 4 – 3 million years ago, also ...

The long-haired rat is well known for its population irruptions over vast areas of Australia which is the basis of its alternative common name, the plague rat. [3] Most of the research on the long-haired rat has been conducted during times of massive population fluctuations and therefore little is known about their biology in a non-eruptive period.
The light-dark box test (LDB) is a popular animal model used in pharmacology to assay unconditioned anxiety responses in rodents. [1] The extent to which behavior in the LDB measures anxiety is controversial.
