Coronavirus testing looks for signs of a coronavirus infection in nasal secretions, blood, or other body fluids.
Swab test. A health care provider will use a special swab to take a sample from your nose or throat.
Nasal aspirate. A health care provider will inject a saline solution into your nose, then remove the sample with gentle suction.
Tracheal aspirate. A health care provider will put a thin, lighted tube called a bronchoscope down your mouth and into your lungs, where a sample will be collected.
Sputum test. Sputum is a thick mucus that is coughed up from the lungs. You may be asked to cough up sputum into a special cup, or a special swab may be used to take a sample from your nose.
Blood. A health care professional will take a blood sample from a vein in your arm.
