The CDC announced it had begun sending new coronavirus testkits to the public, but there are limited numbers.

It comes after news that the CDC is developing a test kit that will allow more labs to test samples from suspected cases in 2019-nCoV. According to the CDC, the agency has been shipping the tests since Thursday, but has only “selected u.S. domestic and international laboratories.” The CDC says about 200 test kits are available in u.S. laboratories, and about the same number will be sent to international laboratories.

Each of these test kits will be able to test approximately 700 to 800 samples collected from patients. The CDC says it is currently producing more test kits and will order them through its international reagent resources. Laboratories where test kits can be ordered include the World Health Organization’s Global Influenza Surveillance and Response System.

In the United States, 115 laboratories are authorized to order coronavirus testing kits that are not approved by the FDA. The test kit can be used without emergency permission because it is an emergency. However, according to the CDC, they can only be used “when there is a proven emergency use authorization.”

In addition to the 115 eligible U.S. laboratories that can order test kits, the CDC says there are 191 eligible laboratories in other countries around the world. The test requires a sample of the patient’s upper and lower respiratory system;
