“Last week, Lake County surpassed 20,000 cases and tragically, 500 deaths from COVID-19. Our thoughts are with every family battling this illness or grieving the loss of a loved one,” said Mark Pfister, Executive Director at the Lake County Health Department.

“Help care for your community by getting tested right away if you are experiencing symptoms, or 5-7 days after being exposed to an infected person and remember to stay home while waiting for your results. Identifying new cases is the start of the contact tracing process that helps to slow the spread of this disease.”

Know Before You Go
Testing is free and open to all regardless of symptoms. A phone number and name are required in order to receive testing results. Photo identification and proof of insurance are helpful, but not required. High demand for testing may result in long wait times. Testing locations may close early due to inclement weather or if daily testing supplies are exhausted. Those utilizing drive-thru testing must be seated at a functioning window. Once you get in line at the site, you will not be permitted to exit your car. All sites will also accommodate walk-up individuals.

Note that testing at the Highwood Public Library is walk-up only. Only viral testing is provided at the mobile testing site.

Other Testing Options
State-run Community-Based Testing Sites, located in Waukegan (102 W. Water St.) and Arlington Heights (2000 W Euclid Ave.) are open 7 days a week from 8 a.m. until 4 p.m. Testing at these sites is free. For more information, visit the IDPH website at

Many healthcare providers in Lake County also have COVID-19 testing available. Please contact your provider or the facility to ask about testing criteria and appointment availability. Residents without a healthcare provider or insurance can contact the Lake County Health Department and Community Health Center for an appointment at (847) 377-8800.

Types of Testing
Viral (polymerase chain reaction or PCR) testing, commonly done with a nasal swab, is used to detect a current COVID-19 infection. This is the only type of test offered at the IDPH mobile testing site and at state-run Community-Based Testing Sites.

Antigen (nucleic acid amplification test or NAAT) testing, done via nasal swab or saliva sample, is a rapid test used to identify current COVID-19 infection. Results are available in as little as 15 minutes, but antigen tests may be less sensitive than a PCR test. This means an antigen test is more likely to produce a false negative test result, especially if the person tested has no symptoms.

Antibody (serology) testing, a blood test, might tell you if you had a past infection and may not detect current COVID-19 infection, so it is NOT an appropriate test for someone who is currently in quarantine for potential COVID-19 exposure.

If you are told to quarantine for 14 days due to a potential exposure to an infected person, a negative COVID-19 test result does not shorten your quarantine period. The virus can take up to 14 days to be detectable in the body by a test, so it is important to continue the quarantine period through 14 days while monitoring for symptoms.  

Additional Information
All residents are urged to continue to follow the 3Ws to slow the spread of COVID-19:

Wear a mask
Wash your hands
Watch your distance
