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.
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.
80% of respondents reported they had undertaken daily rapid lateral flow testing (data collected 31 Jan – 5 Feb 2022). This was significantly higher than the 70% who were surveyed between 10 and ...

Quidel's "Sofia 2 SARS Antigen FIA" [66] [163] is a lateral flow test that uses monoclonal antibodies to detect the virus's nucleocapsid (N) protein. [164] The result is read out by the company's Sofia 2 device using immunofluorescence. [164] The test is simpler and cheaper but less accurate than nucleic acid tests.
