COVID-19 Diagnosis and Treatments

Last updated: August 3, 2021

To confirm a diagnosis of COVID-19, your provider may use a swab in your nose or throat to collect a sample of your respiratory secretions. A lab will then determine if the sample contains the virus that causes COVID-19.

However, it is important to note that not everyone who has symptoms of COVID-19 will be tested. Your care provider will determine if testing is required. Even if you do not get tested, if you have symptoms of COVID-19, you should follow all precautions as though you have the infection.

Northwestern Medicine requires a physician order for COVID-19 testing. A list of the current testing locations and details can be found here. These locations and hours are subject to change. Please discuss your preferred testing location with your physician.


What to Do If You Feel Sick

Call your physician’s office for guidance about testing and treatment if you have symptoms of COVID-19.
Do not go to your physician’s office before calling. You could risk infecting others.
If you are having serious trouble breathing, go to the emergency department or call 911.
