Just as an aside: "accuracy" is a pointless measure if you don't also know the ratio of true cases to false cases. The metrics you really want is the True/False

Just as an aside: "accuracy" is a pointless measure if you don't also know the ratio of true cases to false cases. The metrics you really want is the True/False Positive rates - without that you can't gauge the quality of a test like this.
- SteveHawk27 7y agoQuite so. The data I got is that among the people who really got the virus, positive rate of the test is only 30% - 50%. So false negative rate is as high as 50-70%.

- funklute 7y agoOuch, that is pretty disappointing numbers :(
- SteveHawk27 7y agoYeah. It's not that bad outside Wuhan, people who infected will get top level treatment, there will be best experts doing the diagnostics. But for Wuhan, where medical resources are extremely in short, we can only pray for the people there. Hope it's gonna be better.
