Rapid COVID-19 tests being considered for a rollout by the Victorian government could miss one out of every four infected people.
The data, published by the Doherty Institute for Infection and Immunity on Wednesday, raises questions about how useful the tests would be in a country such as Australia where there is very little virus.In testing of 2413 people without the virus and 22 with infections confirmed by polymerase chain reaction testing, the PanBio test, manufactured by Abbott, missed seven infections and produced one false positive.

The corporate takeover/police state dystopian nightmare we now face, is more real. Funny thing is, Australia was the first to make a rapid test equipment, the U.S.A took it on board and use it with approval of the FDA, why do we reject our own marvellous inventions?
