GRAND RAPIDS, Mich. (WOOD) — Mercy Health is offering two COVID-19 drive-thru testing centers in West Michigan as numbers continue to rise in the area.

One testing site is in Grand Rapids and the other is in Muskegon.

Mercy Health says hundreds of patients can be tested per day from their cars, which reduces potential exposure to others. Patients must be referred by a health care provider to receive testing.

Those who suspect they might have COVID-19 can take a virtual screening on Mercy Health’s website. They may be referred for a virtual visit or to see a health care provider who can order a test if necessary.

If a test is ordered, you’ll be directed to a site.

“They pull into a spot … they’ll be greeted by a nurse,” Mercy Health infectious disease specialist Dr. Andrew Jameson explained. “We have a lab tech here that will check them in, who will get them registered like a normal outpatient lab. Once they get that happening, the nurse will perform the swab and the patient will be on their way.”

The Grand Rapids testing location is at Mercy Health Saint Mary’s in the Wege Parking Ramp at 300 Lafayette Avenue SE. The site is open Monday through Friday from 8 a.m. to 5 p.m. and is also open on Saturdays from 8 a.m. to 12 p.m.

Muskegon’s testing location is at Mercy Health Mercy Campus at 1500 E Sherman Boulevard. The site is open Monday through Friday from 8 a.m. to 5 p.m. and on Saturdays from 9 a.m. to 1 p.m.

Test results are available within 24 hours.

More information can be found on Mercy Health’s website.

Kalamazoo County is also opening a sample collection site for testing at the health department building. It is by appointment only; you must be referred by your doctor before going there.
