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.
The Rat tests used 180 kilograms (400 lb) of uranium-238; 2,160 curies (80,000 GBq) of scandium-46, a beta and gamma emitter with a radioactive half-life of 83.8 days; 400 curies (15,000 GBq) of polonium-210, with a half-life of 138 days; and 120 curies (4,400 GBq) of lead-212, a beta emitter with a half-life of 10.6 hours. With such short ...

Vehicle inspection in Australia is generally done on a state basis (with the exception of Federally Registered Heavy Vehicles, see below). Each state or territory has the authority to set its own laws pertaining to vehicle inspections, all (with the exception of the self-governing territory of Norfolk Island) have some form of inspection, either periodically or before a transfer of ownership.
During his first tests, he placed around 32 to 56 rats in a 10-by-14-foot (3.0 m × 4.3 m) cage in a barn in Montgomery County. He separated the space into four rooms. Every room was specifically created to support a dozen matured brown Norwegian rats. Rats could maneuver between the rooms by using the ramps.
Figure 2 The five primary extant populations of the plains rat as recognised by the 2012 National Recovery Plan.. The primary extant population of the plains rat can be divided into five broad geographic zones: 1) the Arcoona Tableland, SA; 2) the Southern Lake Eyre region, SA; 3) the Moon Plain region, SA; 4) the Oodnadatta region (including Witjira National Park), SA/NT; and, 5) the Andado ...
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.
