COVID-19 rapid antigen tests or RAT s, also frequently called COVID-19 lateral flow tests or LFT s, are rapid antigen tests used to detect SARS-CoV-2 infection (COVID-19). 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 COVID-19 Antigen Rapid Test is a rapid membrane-based lateral flow immunoassay for the qualitative detection of SARS-CoV-2 antigens in human nasopharyngeal swab specimens.
7 wrz 2023 · Antigen tests, often referred to as rapid tests or, for some, at-home or self tests, which detect proteins called antigens from the virus. Samples for COVID-19 diagnostic tests are typically...
6 lis 2024 · At-home over-the-counter (OTC) COVID-19 antigen tests, often referred to as rapid tests, detect proteins called antigens from SARS-CoV-2, the virus that causes COVID-19.
Antigen tests* are rapid tests that usually produce results in 15-30 minutes. Positive results are accurate and reliable. However, in general, antigen tests are less likely to detect the virus than NAAT tests, especially when symptoms are not present.
Rapid tests, also known as rapid diagnostic tests or RDTs, are easy-to-use tests that provide quick results, usually in 20 minutes or less. Most standard tests have to be sent to a lab, and you have to wait for the results.
RATs are a type of lateral flow test detecting antigens, rather than antibodies (antibody tests) or nucleic acid (nucleic acid tests). Rapid tests generally give a result in 5 to 30 minutes, require minimal training or infrastructure, and have significant cost advantages.
