On Wednesday afternoon, the Cleveland Clinic announced that the W.O. Walker Cleveland Community COVID-19 Testing Site now requires an appointment (previously the site required registration but no appointments). This information comes after the site was completely overwhelmed on its opening day.
There's a lot of new information coming with this announcement. If you arrive more than 15 minutes before your scheduled appointment time, then you will have to leave and come back, and they cannot accept anyone who doesn't have an appointment. The high demand for a testing site like this comes at a time when most places are sold out of the at home testing kits. You can read more about the drive-thru testing site and schedule an appointment here and find other testing sites here.
