Why are 90% of the tests negative?
Does that mean 90% of the people isolating with symptoms dont have covid?
Even allowing for 10% duplicate or double checking tests, that's a hell of a lot of "no you dont have it"
Is this a good thing or a bad use of testing resources? |

Could be genuine negative tests - people are not infected or they are not taking the test during the symptomatic period when viral RNA will be detectable.
Or false negative - swabs not inserted far enough to get enough/any sample. Home test kits and most of the drive thru testing is self swabbing - I can guarantee that most people will not push the swab far enough down their throat or up their nose as its pretty unpleasant. More likely to get properly sampled tests if a trained professional does the swabbing.
A lot of people are probably isolating without need, because the symptoms that provoke the isolation are so generic that they could be many different viral illnesses or other conditions. |

You isolate as a precaution to stop the spread the tests are inaccurate anyway they look for coronavirus as in the family off viruses not the specific strain in this case covid 19 |

He is asking a question where does he even suggest if he preferred if they were positive?
What is wrong with some people on here.
Honestly man

It depends on the centre. Some are being done by armed forces (not nurses in the forces) and others are giving the swab to the occupant to do themselves. |

And I’m asking him a question as he seems to be suggesting that negative tests are a waste of resources. |

This is not correct. The tests look for the SARS-CoV-2 viral RNA. This is incredibly specific, because that RNA is exclusive to that specific virus. |

Or just a common cold, as soon as they reach a raised temperature they will panic and want to be tested, also don't forget the people who just want to be tested and lie about having symptoms in order to have one done |

Yes, that was my question.
Nowhere did I say I wanted more positive tests. I personally think it's a good sign that 90 % are negative.
But surely shouldn't it be more like 50 50 negative to positive?
Lots of news about "I need a test but cant get one" yet 90% of tests are negative. Shouldn't they be more targeted?
By the way everytime I've looked at booking a test (I'm allowed one as classed as a key worker) there has been availability in all areas.
I've not booked one as I have no symptoms, yes I could be asymptomatic, but so could everyone. I would rather leave capacity for others.
I will get an antibody test though when available, think these will be much more useful. |

Good points, but dont think 90% (80 to allow for retests) covers the colds and liars though. Just seems a high percentage. |
