The drive-thru test center is operated by private healthcare company Rocdoc and offers the service to people who have not been referred by a doctor. A walk-in test center will open next week and the combined centers will allow Dublin Airport to process up to 12,000 tests per day in the run up to Christmas. Photo by Sam Boal/RollingNews.ie.
