This is news. Actually what is the definition ‘accuracy’? Sensitivity or specificity? And does that mean S Korea having many false +ve or false -ve cases?

So many questions, still no reliable rapid test kits. Curious to know the Singapore batch now. https://twitter.com/kkmputrajaya/status/1245641723805483008

I assume less accurate means less sensitive, resulting in false negatives. If that is the case, then these kits won’t be good for mass testing.
