COVID-19 test

COVID 19 - Nasopharyngeal swab; SARS CoV-2 test

Testing for the virus that causes COVID-19 involves taking a mucus sample from your upper respiratory tract. This test is used to diagnose COVID-19.

The COVID-19 virus test is not used to test your immunity to COVID-19. To test if you have antibodies against the SARS-CoV-2 virus, you need a COVID-19 antibody test.

COVID-19

Infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes COVID-19, a respiratory illness that ranges from mild symptoms to pneumonia or even death. Symptoms occur within 2 to 14 days from exposure to the virus and may include fever, cough, and shortness of breath. COVID-19 may be more severe in people who are older or who have chronic health conditions, such as heart disease or diabetes.

Respiratory system

Air is breathed in through the nasal passageways, travels through the trachea and bronchi to the lungs.

Upper respiratory tract

The major passages and structures of the upper respiratory tract include the nose or nostrils, nasal cavity, mouth, throat (pharynx), and voice box (larynx). The respiratory system is lined with a mucous membrane that secretes mucus. The mucus traps smaller particles like pollen or smoke. Hairlike structures called cilia line the mucous membrane and move the particles trapped in the mucus out of the nose. Inhaled air is moistened, warmed, and cleansed by the tissue that lines the nasal cavity.
