Testing for COVID-19
A guide to help you make decisions and seek appropriate medical careSelf-Check
There are laboratory tests that can identify the virus that causes COVID-19 in respiratory specimens. State and local public health departments have received tests from CDC, whereas medical providers are getting tests developed by commercial manufacturers.
How to decide if you should be tested or seek care
Not everyone needs to be tested for COVID-19. Here is some information that might help you make decisions about seeking medical care or testing.
- Most people have mild illness and are able to recover at home without medical care. They may not need to be tested.
- There is no treatment specifically approved for people who have COVID-19.
CDC has guidance for who should be tested, but decisions about testing are at the discretion of state and local health departments and/or individual clinicians.
- Clinicians should work with their state and local health departments to coordinate testing through public health laboratories, or work with clinical or commercial laboratories.
How to get tested
COVID-19 testing differs by location. If you have symptoms of COVID-19 and want to get tested, call your medical provider first. You can also visit your state or local health department’s website to look for the latest local information on testing. While supplies of these tests are increasing, it may still be difficult to find a place to get tested.
What to do after you are tested
- If you test positive for COVID-19, know what protective steps to take If you are sick or caring for someone .
- If you test negative for COVID-19, you probably were not infected at the time your specimen was collected. However, that does not mean you will not get sick. It is possible that you were very early in your infection when your specimen was collected and that you could test positive later. Or you could be exposed later and then develop illness. In other words, a negative test result does not rule out getting sick later.
Community transmission of COVID-19 is occurring in parts of the United States. In the coming months, most of the U.S. population will be exposed to this virus. You should continue to practice all the protective measures recommended to keep yourself and others from getting infected. See how to protect yourself.
