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.
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 or RATs, also frequently called COVID-19 lateral flow tests or LFTs, are rapid antigen tests used to detect SARS-CoV-2 infection . They are quick to implement with minimal training, cost a fraction of other forms of COVID-19 testing , and give users a result within 5–30 minutes.
The first rodent behavioral study was carried out in 1822, a purely observational study [2], while quantitative rodent behavioral testing began in the late 19th century [1] [2]. Currently, rodents are commonly used in animal testing for physiological, pathological and behavioral scientific studies, particularly mice and rats , but also guinea ...

This paper influenced government and academic circles, and was adopted by e.g. Brimblecombe for his study of atmospheric arsenic levels. [2] The critical review in 1982 by Mitchell and Tilson, [ 3 ] caused the US EPA to develop guidelines for several behavioural tests including a test series based on the Irwin Screen, named the Functional ...
The LDB apparatus has two compartments. The light compartment is 2/3 of the box and is brightly lit and open. The dark compartment is 1/3 of the total box and is covered and dark. A door of 7 cm connects the two compartments. [2] Rodents prefer darker areas over lighter areas.
The two adult forms of the RAT consist of 30 items each. The respondent is allowed 40 minutes to complete the test. Each item provides three stimulus words that are remote from one another; the respondent is then required to find (via the creative process) another word that is a criteria-meeting mediating link, which can be associated with them all in a meaningful way.
