Hy-Vee is expanding its free COVID-19 testing to 150 more stores.

The grocery store chain stated that the tests are free and are administered via a Hy-Vee pharmacy drive-thru testing process. People do not have to have coronavirus symptoms to be tested, but they must register online to receive a test voucher number, testing site and appointment time. The COVID-19 tests are being coordinated by eTrueNorth.  Hy-Vee says each pharmacy location will be able to do up to 12 tests an hour.

Tests will be offered Tuesday, Thursday, and Saturday mornings at Hy-Vee locations in Austin, Albert Lea, Kasson, Owatonna, Winona, and also at the Crossroads Hy-Vee and West Circle Hy-Vee in Rochester.

Hy-Vee says the free test takes about five minutes and results will be sent by email in three to five business days.

The free test program began at 11 locations in August.
