Logan Airport in BOS in a few weeks will open a testing site for travelers....three types of testing available at a price.

.. Nasal swab PCR test for $75...results in 1-3 days

....Rapid molecular test...$200...results in 15 minutes

...blood antibody test...no cost listed

I guess if depends on whether you are arriving and need a quick negative test to avoid quarantine or departing at a future date to a location that needs the PCR test...
