Also known as: Rapid Antigen Test, Rapid Diagnostic Test, RDT
Seek urgent medical care if you experience trouble breathing, persistent pain or pressure in the chest, new confusion, inability to wake or stay awake, or pale, gray, or blue-colored skin, lips, or nail beds.
This test checks for special proteins from the COVID-19 virus. We find these proteins in a sample from your nose. If these proteins are found, it means you probably have COVID-19 right now.
Your doctor orders this test to find out if you have COVID-19. This is especially true if you feel sick or have been near someone with the virus. It helps doctors quickly check many people.
COVID-19 antigen tests give a positive or negative result. The meaning of these results can depend on your symptoms, exposure, and how common COVID-19 is in your area. Results can vary by test kit and manufacturer.
