Facts About COVID-19 Tests
You may be tested using the diagnostic test developed by the Centers for Disease Control and Prevention (CDC). If you receive a negative result, that means that the coronavirus that causes COVID-19 was not found in your sample. However, if you are in the early stages of infection, the virus may not be detected in your sample. If that is the case, you can still spread the virus to others, even if you do not have symptoms.
If you have symptoms but test negative for COVID-19, it is likely that COVID-19 is not causing your current illness.
The process and locations for testing vary from place to place. Contact your state, local, tribal, or territorial department of health for more information, or reach out to a healthcare professional. (State and local public health departments have received tests from the CDC while healthcare providers are getting tests developed by commercial manufacturers.)
Beware of Scam Testing
Some companies are marketing fraudulent test kits that claim to test for COVID-19 in the home.
The FDA is actively and aggressively monitoring for any companies that may be selling products with false COVID-19 diagnostic, prevention, and treatment claims.
