If you have symptoms and think you might have COVID-19, you can ask your health care provider to be tested or schedule an appointment at a COVID-19 testing site in your community. Knowing you have COVID-19 is important so you can take care of yourself and prevent the spread of the virus.

Your health care provider may decide to have you tested for other illnesses, like the flu, based on your symptoms and possible exposure history.

If you are not vaccinated and have been exposed to COVID-19, testing is still recommended.

If you’re not feeling well, consider using the Coronavirus Checker. This tool allows people to check their symptoms, and if warranted, directs them to the appropriate hospital or clinic. It is available by mobile device in 15 languages.

Are the tests accurate?

Two types of tests are typically used: 

  • The polymerase chain reaction (PCR) molecular test is highly accurate when properly performed by a health care professional, but the rapid PCR test can miss some cases.
  • The antigen test detects certain proteins in the virus. This is the rapid version used on college campuses, workplaces, and entertainment venues. A positive antigen test result is accurate when instructions are carefully followed, but these tests have a higher chance of false negatives and to a lesser extent false positives. 

If you or a member of your family tests positive with a rapid test and you’re having symptoms, it’s probably accurate. If you have a negative antigen test result but are having symptoms, you should get a PCR test or retest with a rapid test again the next day. In the meantime, please wear a mask, wash your hands frequently, and avoid exposing yourself to anyone else. 

If you are visiting an at-risk family member or are attending a large public indoor event, you should test yourself a few days in a row to make sure you’re in the clear.

Frequently Asked Questions


If you don’t have a health care provider, call 211 for a list of clinics near you. They can help you even if you don't have insurance. If necessary, visit your local urgent care center. 

You can also call the Clackamas County Health Centers at 503-655-8471 to enroll as a new patient. If you don’t have insurance, they can provide assistance with Oregon Health Plan enrollment. 


Your health care provider will give you information about how to keep from spreading the virus to your family, friends and co-workers and Public Health will call to find out how the coronavirus may have spread. You will need to Quarantine from other people for as long as they instruct. You will also need to avoid coughing on others and to wash your hands frequently to protect them from infection. When you speak to Public Health, be open and honest with them to limit the spread of COVID-19.

Even if you don’t have symptoms:

  • Stay home until:
    • You have no fever for 3 days;
    • Your symptoms improve; AND
    • At least 10 days have passed since your first symptoms (or your test if you are symptom-free).
  • Have other members in your household stay home for 14 days after you are released from isolation.

Talk to Public Health
You’ll get a call from a public health worker who will give you information about what your test results mean and how to protect yourself and those around you until you are not contagious. They can also help you figure out what kind of support you need to isolate yourself and can connect you to organizations that can help with other resources and services you may need, such as groceries, financial support, help with rent or other essential items.

Here is what to expect when you hear from Public Health:

To protect your privacy, they will ask you to confirm your name and birthdate.

They will ask you about the people you have been in close contact with recently.

They will never ask you to provide other personal information (Social Security number, documentation status or financial information).


It varies depending on which laboratory was used, ask your health care provider. Isolate yourself during this time to limit the possible spread of the virus. 


If you think you’ve been exposed, stay home and quarantine regardless of if you are symptomatic or not. If you get sick, we encourage testing.


We do not support requiring proof of negative COVID-19 test results as a condition of reopening or returning to work, especially in light of limited testing capacity at this time.

When someone tests positive for COVID-19, local public health officials will work directly with them on a time-based approach to determine when they may safely return to work after illness. Therefore, a COVID-19 test to return to work is duplicative and not necessary.

However, we may recommend return to work testing for employees of long-term care facilities.
