Healthcare providers commonly use antigen tests to screen and diagnose COVID-19, especially in situations requiring swift outcomes. The COVID-19 antigen test functions by detecting distinct proteins from the SARS-CoV-2 virus in respiratory samples, like nasal or throat swabs. These tests are recognized for their speedy results, often available in 15 to 30 minutes. Their value lies in swiftly pinpointing potentially infectious individuals, enabling prompt implementation of public health actions such as isolation and contact tracing.
