Testing for COVID-19

Why Get Tested

Testing saves lives. Testing can help identify the cause of your illness, allowing you to receive appropriate treatment, if eligible, and take necessary precautions to keep the virus from spreading. Infected people without symptoms can still spread the virus. 

When to Get Tested

  • Test when you feel sick. COVID-19 has a wide range of symptoms, so if you’re not feeling well, it’s best to get tested as soon as possible. See What to Do When You Are Sick With COVID-19 or Another Respiratory Virus for information on what to do if you have COVID-19 symptoms.
  • Testing can be helpful after you’ve been exposed to someone who has symptoms or tested positive for COVID-19. See U.S. Food & Drug Administration (FDA) guidance for more information about the risk of false-negative test results and how to use repeat testing after exposure. 
  • Consider getting tested before gathering with others, particularly if you’ll be around people at high risk of severe illness/disease. Note, false negatives are possible; false positives are uncommon.

Who Can Be Tested?

Anyone can get tested for COVID-19, no matter their age. At this time, the U.S. Food & Drug Administration (FDA) has not approved or authorized any at-home COVID_19 rapid antigen test for use in children under two years of age. However, at-home rapid antigen tests may be safely used in children under two after being exposed, if they are experiencing symptoms, or to identify COVID-19 infection to begin isolation. DOH recommends parents or guardians deciding to test children under age two administer the at-home rapid antigen test themselves.

Because the FDA has not approved or authorized at-home COVID-19 rapid antigen tests for use in children under two years, K-12 schools and child-care facilities with a waived medical test site license are not permitted to perform these tests. However, K-12 schools and child-care facilities may provide at-home rapid antigen tests to parents or caregivers for use on children under two years.

For specific instructions on testing children, please refer to the user guide included with the test kit. For example, iHealth instructions state: “With children, the maximum depth of insertion into the nostril may be less than 3/4 of an inch, and you may need to have a second person to hold the child’s head while swabbing.”

Where to Get Tested

Contact your healthcare provider or local pharmacy to inquire about their testing services. can also check with your local health department or district. For additional information on testing sites, call the Department of Health (DOH) information line: 1-800-525-0127. Language assistance is available.

  • Over-the-counter test kits are available to purchase from online retailers and in pharmacies for convenient, at-home testing.

Types of Tests

The two main types of tests available to detect current COVID-19 infection are rapid antigen tests and molecular Polymerase Chain Reaction (PCR) tests. See COVID-19 Testing: What You Need to Know (CDC) for more information.
