Likely something like how this at home mail in test handles those exact same risks: https://www.cologuardtest.com/ https://www.cologuardtest.com/ The sample is sealed inside a heavy grade plastic container with a screw top lid.

I suspect something similar for this new LabCorp test, just customized for a swab.
