During a White House press briefing on the state of the COVID-19 pandemic in the U.S., members of the White House coronavirus task force provided updates about the current state of coronavirus testing in the U.S., which is a crucial metric to track given that the World Health Organization has said that testing is perhaps one of the most important parts of any effective method of combatting the outbreak.

“As we talked about earlier this week, the commercial system is rapidly advancing in the testing capabilities,” explained task force member Admiral Brett Giroir. “As of today our public health laboratories, meaning the CDC and the public health labs, have reported out 31,878 tests so almost 32,000 tests. The clinical laboratories, the Association of Clinical Laboratories, have reported out about 27,000 tests, and most importantly of those 27,000 during the cumulative period of time 8,200 of them were yesterday.”
