WSJ has an article today saying that tests being used in the US has a 1/3 false negative rate.  Article is paywalled--I just saw a snippet. https://www.wsj.com/articles/questions-a..._lead_pos3

The Chinese test supposedly has a high false-negative rate, too.  https://www.nytimes.com/2020/04/01/well/...ative.html  A quick search did not turn up any comparable numbers for the WHO test.

I realize that false negatives don't necessarily make a test useless.  But if we are going to get to the containment phase, it will be important to have a good test.

Sounds like the tests these days aren't as bad as 1/3 false negative.   However, Abbott's 5-13 minute fast test apparently has a (industry leading?) 84% false negative rate when samples are combined with certain virus transport media.
