The push to increase testing in the U.S. for the novel coronavirus that causes Covid-19 has hit a new stumbling block: shortages of key chemicals needed to start up and run the tests.
In particular, one key product, made by the diagnostics testing giant Qiagen, is in dwindling supply. The chemical is used to isolate the virus’ genetic material, or RNA, so that it can be tested.
Robert Redfield, the director of the Centers for Disease Control and Prevention, told Politico, which first reported the story, that he is worried about the supplies labs have of the chemicals, known as reagents.
“The availability of those reagents is obviously being looked at,” Redfield said Tuesday. “I’m confident of the actual test that we have, but as people begin to operationalize the test, they realize there’s other things they need to do the test.”
