Rapid antigen tests are powerful tools in the fight against infectious diseases, providing quick and reliable detection of specific viral antigens. These tests involve swabbing the nose or throat to collect samples, which are then analyzed for the presence of antigens associated with the target pathogen, such as SARS-CoV-2. Results are typically available within minutes, enabling prompt identification of infected individuals and immediate implementation of isolation measures to prevent further spread. Rapid antigen testing is widely used in healthcare settings, workplaces, travel, and community screening programs to support effective disease management and containment efforts.
