In late April, Dr. Fauci said the US might be able to test 400,000 to 600,000 people per day sometime in May, and testing is now close to that range. This might be enough to allow test-and-trace in some areas.
However, the US might need more than 900,000 tests per day according to Dr. Jha of Harvard’s Global Health Institute.
There were 399,479 test results reported over the last 24 hours.

This data is from the COVID Tracking Project.
The percent positive over the last 24 hours was 5.3% (red line). The US probably needs enough tests to keep the percentage positive well below 5%. (probably much lower based on testing in New Zealand).
NOTE: A few states are apparently including antibody tests with virus tests. The Covid tracking project is working to straighten that out.
