Self-Testing At Home or Anywhere

Self-Testing At Home or Anywhere

For doing rapid COVID-19 tests anywhere

Updated Mar. 9, 2022

What is a Self-Test or At-Home Test?

Self-tests for COVID-19 give rapid results and can be taken anywhere, regardless of your vaccination status or whether or not you have symptoms.

  • They detect current infection and are sometimes also called “home tests,” “at-home tests,” or “over-the-counter (OTC) tests.”
  • They give your result in a few minutes and are different from laboratory-based tests that may take days to return your result.
  • Self-tests along with vaccination, wearing a well-fitted mask, and physical distancing, help protect you and others by reducing the chances of spreading COVID-19.
  • Self-tests do not detect antibodies which would suggest a previous infection and they do not measure your level of immunity.

How to Use an At-Home COVID-19 Test

Read the complete manufacturer’s instructions for use before using the test.

  • To use an at-home test, you will collect a nasal specimen and then test that specimen.
  • If you do not follow the manufacturer’s instructions, your test result may be incorrect.
  • Wash your hands before and after you collect a nasal specimen for your test.

What Your Test Results Mean

IF YOUR TEST IS

Positive

  • The test detected the virus and you have an infection.
  • Stay home for at least 5 days and isolate from others in your home.
  • Tell your close contacts.
  • Wear a well-fitted mask when around others. If available, a N95 or KN95 respirator is recommended.
  • Watch for symptoms. If you have any emergency warning signs, seek emergency care immediately.
  • Tell your healthcare provider. Contact them as soon as possible if:
IF YOUR TEST IS

Negative

  • The test did not detect the virus, but doesn’t rule out an infection.
  • Some self-tests are designed to be used in a series (also known as serial testing). Consider repeating the test 24 to 48 hours later. Multiple negative tests increases the confidence that you are not infected with the virus that causes COVID-19.

If you think your test result may be incorrect, contact the test manufacturer for assistance, consider taking another at-home test, or contact a healthcare provider for help.

Positive results from self-tests are highly reliable.

Negative results from self-tests do not rule out SARS-CoV-2 infection. A negative self-test result may not be reliable, especially if you have symptoms associated with COVID-19.

Invalid results from self-tests mean the test did not work properly, and a new test is needed to get an accurate result.

CDC strongly encourages everyone who uses a self-test to report any positive results to their healthcare provider. Healthcare providers can ensure that those who have tested positive for COVID-19 receive the most appropriate medical care, including specific treatments if necessary.

In most jurisdictions, healthcare providers who diagnose COVID-19 are required to report those cases to public health.

The US Government does not want to construct any barriers that would deter the use of self-tests.  COVID-19 surveillance continues to be based on results from laboratory testing. The primary role of case reporting is to allow public health agencies to take actions to mitigate disease spread. The public health community, including CDC, is confident that situational awareness remains strong without receiving self-test results.
