COVID-19 Testing

COVID-19 Free Testing Events

Loudoun County is hosting free drive-thru testing events. The events are expanding to twice a week beginning in January 2022 with a new start time of 9:00 a.m. Testing may begin early to mitigate traffic impacts.

Future Events

To meet the demand for testing and to maximize capacity, the testing events held so far in January have been at the largest of the county’s available facilities for testing, Philip A. Bolen Memorial Park in Leesburg. If demand decreases, the county may return to scheduling events at rotating facilities. We will announce decisions on a week-to-week basis on testing event locations based on demand. That information will be posted here.

About COVID-19 Testing

  1. Types of COVID-19 Tests
  2. Who Should Get Tested?

PCR and Antigen (rapid) Tests

Antibody Testing

  • Antibody tests check for antibodies, which can show if an individual had a past infection with the virus that causes COVID-19.
  • A positive antibody test result shows an individual has antibodies from an infection with the virus that causes COVID-19, or possibly from infection with a related virus from the same family of viruses (called coronavirus), such as one that causes the common cold.
  • Antibody tests should not be used to diagnose COVID-19. A viral test is needed to show a current COVID-19 infection.
  • The CDC does not know yet if having antibodies to the virus that causes COVID-19 can protect someone from getting infected again or, if they do, how long this protection might last.
  • Learn more about antibody testing from the CDC.

Will the Health Department contact me if I get a positive COVID-19 test? 

  • If you test positive for COVID, you may be contacted by a Loudoun County Health Department Case Investigator (usually by phone) for a voluntary and confidential conversation.
  • The case investigator will ask you some questions to understand more about you and your illness. The interviewer will work with you to create a list of all of the people you may have had close contact with while you were sick, and right before you felt sick. This process helps to find people who may have been exposed to COVID-19.
  • After your close contacts have been identified, a contact tracer will reach out and notify them of their possible exposure as soon as possible. When the interviewer calls close contacts, they do NOT tell them who it was who tested positive for COVID-19. This conversation will be confidential to protect and respect your privacy.
  • Both case investigators and contact tracers will also provide education, information, and support to help stop the spread of COVID-19.
  • Read more about case investigations and contact tracing on the Virginia Department of Health website.

Loudoun County COVID-19 Testing Task Force

  • The Loudoun County COVID-19 Testing Task Force was organized to help facilitate the availability of more COVID-19 testing in the community.
  • The Task Force is comprised of health care providers, infectious disease and public health experts, nonprofit representatives, and county officials.
  • Visit the Task Force’s webpage for more information about testing, current Task Force recommendations for antibody testing, and resources from and for physicians.
