GURNEE, Ill.—Inside a factory that is the size of five football fields, thousands of workers from Abbott Laboratories race to meet demand for America’s dominant Covid-19 at-home test.
Some place test strips inside white, rectangular cards of paper that feature a pink stripe, before sealing them into a pouch. In other rooms, workers pack pouches, swabs and solution into bluish-purple boxes labeled BinaxNow. Trucks roll in to pick up new supplies between 3 a.m. and midnight, every day.
