COVID-19 tests

COVID-19 tests identify if someone is currently infected with the virus. There are two main types: molecular (PCR) tests, which detect the virus’s genetic material and are highly accurate, and antigen tests, which identify specific viral proteins and give quicker results but are slightly less sensitive. Both involve collecting a sample via nasal or throat swabs. These tests help control the spread of the virus by detecting active infections early, enabling timely isolation and treatment. Accurate testing is essential for managing outbreaks and informing public health decisions.
