Even the worst tests here provide a lot more information than a coin flip, as I understand it. A 50% PPV at a prevalance of 5% means that if the odds of someone having had coronavirus were 5% going into the test and they get a positive result, you can immediately update your estimate of the odds of them having had it to 50%, which isn't nothing. |
