Test maker targeted by FDA says it responded to US concerns A company targeted by the Food and Drug Administration for selling unauthorized coronavirus antibody tests says it has responded to U.S. regulators' concernsWASHINGTON -- A company targeted by the Food and Drug Administration for selling unauthorized coronavirus antibody tests says it has responded to regulators' concerns, though it has no business operations in the U.S. The Food and Drug Administration announced Wednesday it had sent warning letters to three companies selling at-home blood tests, none of which have been reviewed or authorized by the agency. The tests instead look for blood proteins called antibodies, which indicate someone had a previous infection. Most of the tests use a finger-prick of blood on a test strip. ———The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.
