Test for Current Infection
Viral tests check samples from your respiratory system (such as swabs of the inside of the nose) to tell you if you currently have an infection with SARS-CoV-2, the virus that causes COVID-19. Some tests are point-of-care tests, meaning results may be available at the testing site in less than an hour. Other tests must be sent to a laboratory to analyze, a process that takes 1-2 days once received by the lab.
How to decide if you should get a viral test
To learn if you have a current infection, viral tests are used. But not everyone needs this test.
- Most people will have mild illness and can recover at home without medical care and may not need to be tested.
- CDC has guidance for who should be tested, but decisions about testing are made by state and local health departments or healthcare providers.
- If you have symptoms of COVID-19 and want to get tested, call your healthcare provider first.
- You can also visit your state or local health department’s website to look for the latest local information on testing.
- Although supplies of tests are increasing, it may still be difficult to find a place to get tested.
How to get a viral test
COVID-19 testing differs by location. If you have symptoms of COVID-19 and want to get tested, call your healthcare provider first. You can also visit your state or local health department’s website to look for the latest local information on testing. Although supplies of tests are increasing, it may still be difficult to find a place to get tested.
In late April, the U.S. Food and Drug Administration (FDA) authorized a viral test that lets you collect a respiratory sample at home. However, you will still need to send your sample – a swab of the inside of your nose – to a laboratory for analysis. The home collection kits will be available through healthcare providers in most states in coming weeks.
What to do after a viral test
To get your test result, please check with the group that performed your test, such as your healthcare provider or your health department. Check the CDC website to locate your health department information. How long it will take to get your test results back depends on the test used.
- 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 sample 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 sample 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 mean you won’t get sick later. This means you could still spread the virus. Know How to Protect Yourself and Others.
