False positive rate?  That information is nearly impossible to find. Perhaps this has a reason.        Only this article says:  The accuracy rate of the test is only 30 to 50 per cent, said Wang Chen, president of the Chinese Academy of Medical Sciences, during a CCTV interview on Wednesday.  That's hard to believe, but he has no reason to look worse than necessary. It would mean it's a pure random result. And if a person was tested multiple times, he'll be probably positive in the end, regardless of his health state.  No symptoms yet getting tested?          It seems like they didn't. So it's a fake test?
