| Indeed. There is a discussion about the tests specificity and sensitivity rates (related to the false positive and negative rates) here: https://cy.ons.gov.uk/peoplepopulationandcommunity/healthandsocialcare/conditionsanddiseases/bulletins/coronaviruscovid19infectionsurveypilot/englandandwales14august2020#test-sensitivity-and-specificity I think, in short, they don't really know. The main reason being that there is no "gold standard" to compare the tests against. e.g. for a pregnancy test there is a clear outcome that enables test reliability to be established. Not so with Covid-19. I suggest that Hounslow's Public Health officer has a duty to make public all the relevant data (including false positive and negative rates) backing any decisions they make having an impact on citizens right to free movement and assembly. |
