My organization has put together some data on this: https://covidtestdb.com/performance/ https://covidtestdb.com/performance/ We pulled together performance data for dozens of COVID-19 diagnostics, which you can download. We also created a stats tool to help you understand the Predictive Value of each test based on how widespread the disease is in the tested population. The key metrics we look at are: Positive predictive value (PPV), the fraction of positive tests where the person actually had the disease. Negative predictive value (NPV), the fraction of negative tests where the person actually did not have the disease.
