Coronavirus (COVID-19) Testing

Testing for COVID-19 is available in many locations across Fairfax Health District. If you need a test, contact your health care provider or visit one of the sites listed here.

Who Should Get Tested

Laboratory staff conduct COVID-19 testingIf you have symptoms — even mild symptoms — or have been exposed to someone with COVID-19, get tested. Anyone, whether or not they have symptoms, who has significant exposure to someone who was confirmed to have COVID-19 should also get tested.

People can use the Centers for Disease Control and Prevention’s self-checker or the Virginia Department of Health’s COVIDCHECK to help make decisions on when to call their doctor or seek appropriate medical care regarding COVID-19.

Call your Primary Care Provider

Call your primary care provider to discuss your symptoms and get scheduled for a test. Some primary care providers are set up to test their patients on site. Others are referring patients for testing by appointment at other locations such as Respiratory Clinics and drive-up testing sites. Your primary care provider will talk with you about the best place for you to get tested. They will also let you know how you can get your test results.

Call a Clinic

  • If you don’t have a primary care provider, there are still options for testing.
  • Places such as urgent care centers, community health centers, and community-based clinics across the state evaluate patients who may have COVID-19 and do testing. Most clinics are set up to swab patients for testing on-site and many offer drive-up and walk-up testing options.
  • Some facilities may require you to call ahead before visiting their location. 
  • The clinic will let you know how to get your test results.

When Will I get my Test Results?

3 Key Steps to Take While Waiting for Your COVID-19 Test ResultThe time between when a specimen is collected and when you receive your results can vary depending on the laboratory conducting the testing. With the exception of some rapid tests, it could take from 1 to 7 days, or sometimes longer to get your result, so be sure to check with your provider in advance.

While you are waiting for your test results:

  1. Stay at home and isolate yourself to help protect your friends, family and others from possibly getting COVID-19 from you.
  2. Think about the people you have recently been around.
  3. Answer the phone if we call. Learn more about contact investigations.

What Happens If I Test Positive?

  • Your name and contact information will be shared with public health staff at the Fairfax County Health Department to perform a case investigation.
  • Someone from the Health Department will call you to discuss your illness, answer questions and provide guidance on how to take care of yourself and prevent spreading COVID-19 to other people. Recommendations will include staying home in a separate room (“isolation”), wearing a facemask or cloth face covering if anyone needs to be in the room, washing your hands frequently, and cleaning high-touch surfaces (doorknobs, railings, phones, counters, faucet handles) regularly.
  • The Health Department also will ask you for a list of people you have had close contact with during the period when you could spread the infection. These close contacts also will be asked to stay home and away from others for a 2-week period during which they could exhibit symptoms of COVID-19.
  • Please see When to Isolate and When to Quarantine for more information about how long you and your contacts should stay away from others.
  • If any of your symptoms get worse or if you develop new symptoms, call your healthcare provider.


What Happens If I Test Negative?

  • Your name and contact information will be shared with public health staff at the Fairfax County Health Department.
  • If you test negative for COVID-19, you most likely were not infected at the time of your test. You may have another illness. Follow your healthcare provider’s instructions and whatever treatment they prescribe.
  • It is also possible that you were tested very early in your infection and you could test positive later. Or you could be exposed later and get sick. This means that even with a negative test, it is important that if a new illness develops, you contact your healthcare provider and may need to be tested again.
  • To prevent spreading any infection you have, wash your hands often, cover coughs and sneezes, practice social distancing (six feet between you and other people), and while you are sick, stay home from work.


How Do I Know When to Quarantine?

  • If you have been identified as a contact of someone who tested positive for COVID-19, you may be contacted by the Fairfax County Health Department. A representative of the Health Department will conduct an interview and will provide guidance on whether you need to quarantine and what that quarantine entails.
  • If someone who you were in close contact with tells you that they are sick with COVID-19, please stay at home for 14 days and monitor yourself for symptoms. People who have tested positive are being asked to inform their own close contacts to help stop the chain of transmission. 
  • If you have had close contact with someone who tested positive for COVID-19 and you have not been contacted by Fairfax County Health Department, please stay at home for 14 days and monitor yourself for symptoms.
  • Self-quarantine means:
    • Stay home.
    • Do not go to work, school, or public areas.
    • Do not use public transportation.
    • People in quarantine must distance themselves from others, including at home.
    • Monitor yourself for symptoms.
    • If symptoms develop, isolate at home. Call your healthcare provider. Get a COVID-19 test.
    • If no symptoms develop, you may leave quarantine after 14 days from the date of the last contact with the COVID-19 patient.


What Should Employers Know?

Employers should not require employees to provide a negative COVID-19 test result or a healthcare provider’s note to enable them to return to work. An employee can return to work once either of the following situations is met. 

  1. An employee who had symptoms of COVID-19 illness and infection that was confirmed by a virus test or healthcare provider’s diagnosis is cleared to return to work after:  
    1. At least 24 hours with no fever without the use of medications to reduce fever such as Tylenol, Acetaminophen, Advil, Ibuprofen, Aleve, or Naproxen; AND  
    2. Symptoms have improved and no new symptoms developed; AND
    3. At least 10 days have passed since symptoms started or since the date of the positive COVID-19 test
  2. An employee who never had symptoms of illness and infection that was confirmed by a virus test is cleared to return to work 10 days after the date of the positive test.  

A negative virus test result should not be required because healthcare providers are extremely busy and may not be able to provide such documentation in a timely manner; and because the test may remain positive long after an individual is no longer contagious (unable to spread illness). This is because the test may detect dead virus particles that cannot be spread to others. People who are immunocompromised should check with their doctor before returning to work and healthcare workers should check with Occupational Health provider. This guidance is consistent with recommendations from the Centers for Disease Control and Prevention (CDC) and the Virginia Department of Health (VDH).

Employers shall notify their employees and the Health Department of any reports they receive of positive COVID-19 tests by employees, subcontractors, contract employees, and temporary employees present at the place of employment within the previous 14 days from the date of positive test. This is in accordance with the Virginia Occupational Safety and Health Program and the Virginia Department of Labor and Industry, Emergency Temporary Standard for Infectious Disease Prevention related to COVID-19. Cases should be reported using this form.

If you have any questions, please contact the Health Department’s Call Center at (703) 267-3511.


Testing Overview

There are two types of testing available for COVID-19: 

Type 1: Diagnostic tests.

There are two types of diagnostic tests: molecular tests, such as RT-PCR tests that detect the virus’s genetic material, and antigen tests, that detect specific proteins on the virus. These tests indicate if you have a current infection. Diagnostic tests most often involve a nasal or throat swab. However, there are some new diagnostic tests available with alternative methods, such as a saliva test. Test results may remain positive for days to more than a week.

Type 2: Serologic (or antibody) test.

These tests are conducted to detect COVID-19 antibodies, which your body makes in response to an infection. 

There are two types, one tests for recent infection (IgM) and one tests for past infection (IgG). The performance of these tests varies. These tests are conducted using a blood specimen. IgM becomes positive 4-10 days after infection & IgG becomes positive 10-20 days after infection. Depending on when someone was infected and the timing of the test, the test may not find antibodies in someone with a current COVID-19 infection.


What About the Antibody Test?

Antibody blood tests, also called serology tests, may show if you had a previous infection with the virus. However, medical science has yet to determine what level of antibodies confirm immunity or how long immunity might last. Until there is more definitive information, we should assume, even with positive antibodies, that a person may still be susceptible to the coronavirus.

An antibody test also should not be used to diagnose COVID-19. To see if you are currently infected, you need the viral test.

The Federal Bureau of Investigation is warning the public about potential fraud schemes related to antibody tests for COVID-19. Scammers are marketing fraudulent and/or unapproved COVID-19 antibody tests, potentially providing false results and seeking to obtain individuals’ personal information and personal health information. Not all COVID-19 antibody tests have been approved by the U.S. Food and Drug Administration (FDA), and their efficacy has not been determined. Learn more about this FBI warning.
