Widespread testing for COVID-19 is still not happening in the U.S. Although experts have been urging the federal government since February, it took until late April to ramp up production.
Step 2 takes place at a lab. There, genetic material is extracted from the sample. That requires a special machine and chemicals called reagents.
The COVID-19 testing process has been plagued by missing components, including swabs, reagents and the chemical solution that keeps samples fresh. Some weeks, there are shortages of some but not others, or one location has them and another doesn't. But Trump was wrong. Cotton can interfere with test results because it contains its own genetic material, so nasopharyngeal swabs are typically made of polyester, nylon, foam or some other synthetic material.
"I don't think the United States was prepared," said Timothy Templet, Puritan's executive vice president of global sales."That includes us, Puritan. It includes our customers. And it includes the government ... And now it gets really nerve-wracking to think that we may be in this for another couple years."
