"Good news: Just today, they released new rules that should increase testing capacity by 400x"

How can new rules increase testing capacity? All you can do, is adjust the rules to the existing capacities ...

The capacity basically existed, but couldn’t be used until it had gone through fda certification for the virus. The new rules allow labs to perform testing after sending the required information to the fda but before the fda has had time to review that information

Presumably they have obtained more resources and have updated the rules to reflect that.
