What happens during coronavirus testing? If your provider thinks you may have COVID-19, he or she will contact the CDC or your local health department for instructions on testing. You may be told to go to a special lab for your test. Only certain labs have been allowed to do tests for COVID-19. There are a few ways that a lab may get a sample for testing. 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. The FDA has approved more widespread use of a rapid test for COVID-19. The test, which was developed by the CDC, uses samples from the nose, throat, or lungs. It enables fast, accurate diagnosis of the virus. The test is now allowed to be used at any CDC-approved lab across the country. 有人说只有三个地方可以测，其实是任何CDC批准的实验室都可以。https://medlineplus.gov/lab-tests/coronavirus-testing/ CDC has more than 1700 scientists, working in more than 200 cutting-edge laboratories across the U.S. https://www.cdc.gov/labs/index.html 我觉得CDC的信息非常透明，不了解的可以去查，请不要恐慌
