Diagnostic testing is the throat or mouth swab that has been in use for several months to test whether someone is infectious with COVID-19 at that time.
Who should get tested?
- If you have been in contact with someone infected with COVID-19 or you have symptoms—such as cough, fever, and shortness of breath—call your doctor or health care provider before visiting.
- There is no treatment specifically approved for this virus and most people have mild illness and can recover at home.
- If you think you have been exposed to COVID-19 and are not able to get tested, inform your close contacts and continue to follow preventive measures recommend by the Centers for Disease Control, such as frequent hand washing, avoiding crowds and staying at least 6 feet away from other people.

How do I get tested?
- Health care providers will ask you questions to determine whether you need a COVID-19 test.
- Guidance for COVID-19 testing from the Virginia department of Health is posted online.
- However, it is important to note that individual doctors’ offices, pharmacies and the operators of drive-through testing services may use varying criteria
- For the test, a health care provider will need to collect a specimen, which is a nasal or throat swab that is sent to a lab.
- 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.
