All federal limits on testing will be lifted, Pence says.

Vice President Mike Pence said the Centers for Disease Control and Prevention was lifting all restrictions on testing for coronavirus, and would be releasing new guidelines to fast-track testing for people who fear they have the virus, even if they are displaying mild symptoms.

“Today we will issue new guidance from the C.D.C. that will make it clear that any American can be tested, no restrictions, subject to doctor’s orders,” Mr. Pence told reporters at the White House.

The federal government has promised to significantly ramp up testing, after drawing criticism for strictly limiting testing in the first weeks of the outbreak. But health care supply companies and public health officials have cast doubt on the government’s assurances, as complaints continue that the need for testing remains far greater than the capacity.

“The estimates we’re getting from industry right now — by the end of this week, close to a million tests will be able to be performed,” the head of the Food and Drug Administration, Dr. Stephen Hahn, said at a White House briefing on Monday.
