The FDA has a very streamlined process for authorizing the emergency use of a host of testing kits for the novel coronavirus (2019-nCoV). Some are the classic PCR tests and some are antibody tests (IgM and IgG).
So far there are 30 different tests on the Emergency Use Authorization list. Here is a link to the FDA’s Test Kit Manufacturers Table which includes the manufacturer and their contact information, fact sheets for providers and patients and instructions.
