Covid-19: Government buried negative data on its favoured antibody test | The BMJ

The UK government delayed the findings of a Public Health England (PHE) study that question the accuracy of a leading covid antibody test just as it was about to announce that it had spent £75m (€84.3m; $99.4m) on buying one million of the tests.
The study,1 published online this week at bmj.com, is the first independent assessment of the test and finds it to be significantly less accurate than a manufacturer funded study has claimed. If the test is used in the community as intended, and assuming that 10% of recipients have previously been infected, around one in five positive AbC-19 tests would be a false positive, the findings suggest.
