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 at-home tests typically provide results within 30 minutes or less and can be administered to vaccinated and unvaccinated people. Many COVID-19 tests now have extended expiration dates.
