To test for the coronavirus, you need a swab.
But only two companies in the world manufacture the specialized instrument used to collect a sample from noses.
The limited supply has led to a shortage in the U.S. and a scramble by those two manufacturers to produce more.
One of those companies, Puritan Medical Products, based in Guilford, Maine has ramped up its production to more than 1 million swabs per week, according to Timothy Templet, the company's vice president of sales.
