How this is done here in Czech Republic is by placing a medical tent or a mobile office container on the grounds near the given hospital handling the testing. Then people who are to be tested and are in quarantine at home (mostly after visiting affected areas in Italy and elsewhere or by being traced to someone infected) make appointments over phone, then arrive by private car at the designated time. They will actually not set foot in the tent, instead a swab sample is taken by a medic in full hazmat suit. The tent houses the medic & sample handling equipment. The people who have been tested then return to quarantine at home and wait for the results. This is also compounded by a dedicated ambulance with team in full protective gear that takes samples from people at home.
