COVID-19 Testing

Page last updated/reviewed 3/30/2023.

There are a number of ways you can test to see if you have COVID-19. Contact your healthcare provider, visit your local drug store, or find a testing site in your community. If you do not have a healthcare provider and would like to get connected to one, call 2-1-1. If you have serious symptoms, like difficulty breathing, call 9-1-1.

When to Test

Key times to get tested:

  • If you have symptoms, test immediately.
  • If you were exposed to COVID-19 and do not have symptoms, wait at least 5 full days after your exposure before testing. If you test too early, you may be more likely to get an inaccurate result. 
  • If you are in certain high-risk settings, you may need to test as part of a screening testing program.
  • Considering testing before contact with someone at high risk for severe COVID-19, especially if you are in an area with medium or high COVID-19 Community Level.


Self-test kits, sometimes also called “home tests,” “at-home tests,” or “over-the-counter (OTC) tests,” for COVID-19 detect current infection. 

When to Self-Test

How To Use a Self-Test

Reporting a Self-Test Result

  • Individuals should report their result according to the instructions recommended by the self-test kit.
  • Reporting of a self-test result is not required. However, if you feel you need medical attention, sharing your self-test result with your healthcare provider maybe helpful.

Resources to Get No-Cost, At-Home, Self-Test Kits

Test Results

Regardless of vaccination status, if your test result is:


  • The test detected the virus, and you have an infection.
  • Isolate and take precautions, including wearing a high-quality mask to protect others from getting infected.
  • Tell people you had recent contact with that they may have been exposed.
  • Watch for symptoms. If you have any emergency warning signs, seek emergency care immediately.
  • Contact your healthcare provider, community health center, or pharmacy to learn about treatment options that may be available to you. You are more likely to get very sick if you are an older adult or have an underlying medical condition.
