The COVID antigen test detects viral proteins in a nasal or throat swab to determine if a person is currently infected with the SARS-CoV-2 virus.
Why is antigen test done?
Antigen tests are used for quick identification of active COVID-19 cases, making them valuable for rapid screening in various settings such as schools, workplaces, and healthcare facilities.
How antigen tests work?
Antigen tests detect specific viral proteins using antibodies. The test provides results within minutes, making it a rapid diagnostic tool, but it may have lower sensitivity compared to PCR tests.
What is the difference between PCR and antigen test?
PCR tests detect viral genetic material and are highly sensitive but take longer to produce results. Antigen tests detect viral proteins and provide quicker results, but they may be less sensitive.
