Get tested in San Francisco
Any time you feel sick or have a known exposure, get tested.
Get tested when any of these apply:
- When you have Covid-19 symptoms
- When you’ve had close contact with someone who has COVID-19, test 5 days after your exposure. Testing earlier to find out if you’re positive is optional
- When asked by your school, workplace, doctor, or the Department Public of Health
Think about getting tested in these situations:
- Before and after activities that put you or others at higher risk for COVID-19, like attending large gatherings or being in crowded indoor settings
- When you work somewhere with a higher risk of COVID-19 transmission, like homeless shelters, jails, and settings with close contact with the public. See detailed testing guidance from the State
- Right after a close contact with someone who has COVID-19. Earlier treatments might be open to you, and you can let anyone exposed to you know sooner if your test is positive
No matter your vaccine status:
- For all international travel to the United States, you must get tested within 24 hours of your flight
- For all travel to California from other states or countries, you should get tested 3 to 5 days after you arrive in California
When you’re not vaccinated:
- Fever over 100.4° Fahrenheit or 38.0° Celsius
- Chills (shivering a lot)
- Difficulty breathing
- Fatigue or soreness
- Loss of smell or taste
- Sore throat
- Runny or stuffy nose
- Diarrhea, feeling sick to your stomach, or throwing up
Your child does not have to get tested if they:
- They only have a runny nose
- They have had no close contact with someone with COVID-19

Types of tests
There are 2 types of tests that can tell if you have COVID-19 now:
- Antigen tests
- PCR or NAAT
You can get antigen and PCR/NAAT tests done in a clinic, test site, or lab.
You can also do antigen and PCR/NAAT tests at home. These are called at-home or over-the-counter tests.
An antigen test is better than a PCR test when:
- You want to end isolation
- You have a close contact to someone with COVID-19 but you had an infection with COVID-19 in the last 90 days
This is because antigen testing is better at picking up virus that is still infectious. PCR tests can stay positive for longer than the infectious period.
Antigen tests may miss early infection. If you have symptoms or are a close contact and tested negative, test again in 1-2 days.
There is also an antibody test. This test tells you if you had COVID-19 in the past. These are done in a clinic or lab.
At-home tests tell you if you have COVID-19 now. They cannot tell you if you had an infection in the past.
Get home tests over-the-counter in pharmacies or by mail. You can also get 4 free rapid antigen tests for your household at https://www.covidtests.gov/.
You might not be able to use an at-home test for healthcare purposes or travel. Check any healthcare or travel requirements before you use the test.
At-home tests may be used to return to work, school, or a non-healthcare setting. If your employer asks for a test, please contact your supervisor for instructions about how to report your test results.
There is no printout of your results with most at-home tests. The Department of Public Health (DPH) will not provide a letter of your results. Healthcare providers may not provide a letter because they did not see you do the test.
When you test positive using an at-home test:
- You most likely have COVID-19, even if you don’t have symptoms
- You don’t have to confirm the result by going to a lab, clinic or testing site
- Let your doctor know about your result
- You don’t have to report your positive result to the Department of Public Health
The San Francisco Department of Public Health has more information on when to use at-home self-tests.

If your test is negative, you must still be careful. You can still get infected. Or you could still have COVID-19, but the test does not show you are infected yet. If you have COVID-19 symptoms later, you can get tested again.
