A rapid at-home COVID-19 test is a type of diagnostic test that can be performed at home to detect the presence of the SARS-CoV-2 virus, which causes COVID-19. These tests are typically lateral flow immunoassays, which use antibodies to detect the presence of viral antigens in a sample. Rapid at-home COVID-19 tests are intended to be used as a screening tool to identify individuals who may be infected with the virus, and they should be followed up with a confirmatory PCR test for a definitive diagnosis.
Rapid at-home COVID-19 tests have become increasingly popular due to their convenience and affordability. They are easy to use and can provide results in as little as 15 minutes. Rapid at-home COVID-19 tests have also played a significant role in the fight against the COVID-19 pandemic, as they have helped to identify and isolate infected individuals, thereby slowing the spread of the virus.
