Once a week, after she brushes her teeth and gets ready to leave for work at the Oklahoma Medical Research Foundation, Cindy Carter sets a 30-minute timer on her phone. When Carter’s phone buzzes on her drive, it reminds her of the task that now kicks off her week: submitting a saliva sample for OMRF’s weekly employee COVID-19 testing program. Before leaving her car, Carter opens her testing kit, which OMRF provides to staff members each week. Inside is a cup, a barcoded sample tube, pipette, alcohol wipe and biohazard bag.
