Answer:
COVID-19 can be diagnosed similarly to other conditions caused by viral infections: using a blood, saliva, or tissue sample. However, most tests use a cotton swab to retrieve a sample from the inside of your nostrils.
The CDC, some state health departments, and some commercial companies conduct tests. See your state’s health department websiteTrusted Source to find out where testing is offered near you.
On April 21, the Food and Drug Administration (FDA)Trusted Source approved the use of the first COVID-19 home testing kit.
Using the cotton swab provided, people will be able to collect a nasal sample and mail it to a designated laboratory for testing.
The emergency-use authorization specifies that the test kit is authorized for use by people who healthcare professionals have identified as having suspected COVID-19.
Talk to your doctor right away if you think you have COVID-19 or you notice symptoms.
Your doctor will advise you on whether you should stay home and monitor your symptoms, come into the doctor’s office to be evaluated, or go to the hospital for more urgent care.
