McHenry COVID-19 testing site closed to walk-ins due to high demand

People head inside a McHenry County Department of Health COVID-19 vaccination clinic at 1900 N. Richmond Road, the former site of a Kmart in McHenry, on Tuesday, March 2, 2021.  Vaccinations are made by appointment only.

The Curative COVID-19 testing site at the former Kmart in McHenry will be closed to walk-ins until further notice, the McHenry County Department of Health said Tuesday.

The site at 1900 N. Richmond Road will remain open for testing, but appointments will be required. The health department said the decision to make the location appointment-only is because of high demand for COVID-19 tests at the location.

The site originally was opened and operated by the McHenry County Department of Health as a vaccine site, but the county transferred its operations to Curative in June.

To schedule an appointment for a COVID-19 test at the location, go to or call the McHenry County health department at 815-334-4045.

Congestion at local testing sites in McHenry has increased in the last week. McHenry police said last Tuesday a site at 3815 Elm St. was congested and people who need a test should try to find another location.

The McHenry County health department said people should ask when they will receive their test results before taking the test. It said anyone who has concerns or suspicions about a testing site’s validity can call 800-252-4343 about their concerns. If someone thinks a site is fraudulent, they should contact local police and the Illinois Attorney General’s Office.
