rapid antigen detection test

A rapid antigen detection test is a diagnostic tool used to quickly identify specific proteins (antigens) from a virus or bacteria, such as COVID-19 or flu. When a sample, usually from a nasal swab, is taken and applied to the test, it can produce results within 15-30 minutes. These tests are fast and convenient, providing a helpful way to detect infections early. However, they may be slightly less accurate than lab-based tests, so negative results, especially if symptoms persist, might need confirmation with more sensitive testing.
