Rapid Test

A rapid diagnostic test (RDT) is a medical diagnostic test that is quick and easy to perform. RDTs are suitable for preliminary or emergency medical screening and for use in medical facilities with limited resources. They also allow point-of-care testing in primary care for things that formerly only a laboratory test could measure. They provide same-day results within two hours, typically in approximately 20 minutes. https://en.wikipedia.org/wiki/Rapid_diagnostic_test

COVID-19 rapid antigen tests, also frequently called COVID-19 lateral flow tests or LFTs, are rapid antigen tests used to detect SARS-COV-2 infection (COVID-19). They are quick to implement with minimal training, and offer significant cost advantages, costing a fraction of other forms of COVID-19 testing and give users a result within 5–30 minutes. Rapid antigen tests are used in several countries as part of mass testing or population-wide screening approaches.[1][2][3] They are thought to be valuable for identifying individuals who are asymptomatic and could potentially spread the virus to other people, who would otherwise not know they were infected.[4] This differs from other forms of COVID-19 testing, such as PCR, that are generally seen to be a useful test for symptomatic individuals, as they have a higher sensitivity and can more accurately identify cases. https://en.wikipedia.org/wiki/COVID-19_rapid_antigen_test
