The Food and Drug Administration on Friday authorized a new coronavirus antigen test produced by Quidel Corporation, a California-based diagnostic testing company.

Why it matters: Antigen tests deliver results quickly and are relatively easy to produce, though their results are less accurate than the standard tests the U.S. has been using so far.

What's happening: “We are ramping up manufacturing to go from 200,000 tests next week [week of May 11] to more than a million a week within several weeks,” Douglas Bryant, Quidel’s CEO, told the Wall Street Journal.

  • Quidel has currently provided roughly 36,000 "test-analyzer instruments" in doctors' offices and hospitals, per the WSJ.

Between the lines: Antigen tests create a greater chance of false negatives, CNBC reports, and a negative antigen result may need to be confirmed with additional testing. But, positive antigen test results are usually highly accurate.

The big picture: The U.S. will need coronavirus tests that can detect antigens, or the part of a pathogen that triggers an immune response, as part of a testing breakthrough needed to screen a large number of people for the virus, Deborah Birx, White House coronavirus task force coordinator, said in April.

New Zealand Prime Minister Jacinda Ardern announced all domestic pandemic restrictions will be lifted from midnight Monday and those in Auckland will be eased late Wednesday.

The big picture: Ardern delayed the country's election until Oct. 17 as authorities work to stamp out a coronavirus cluster in Auckland, after the virus' re-emergence in NZ. There have been single-digit or zero domestic cases in NZ's most populous city since the government reintroduced restrictions.

Cruise ship passengers were tested for the coronavirus on Sunday before setting sail for what is believed to be the first Mediterranean cruise since Italy's lockdown, AP reports.

Why it matters: Cruise ships were the source of some of the first coronavirus outbreaks in the world due to the high population density and close quarters that passengers live in. Over 600 passengers on the Diamond Princess were infected with the virus in February.
