This is why we must offer confirmatory rapid tests along w any rapid test program
If we give ppl 20 of test A, we need to give 1-2 of test B - a confirmatory test to use immediately if a pos shows up on A. Can be Ag or Molecular, at home test.

Many rapid tests have False positive rates of 1 in 1000 or less. This is great. But when using huge numbers to control spread, it’s better to have that number at 1 in 10,000 or lower. A simple test A +B if A is positive algorithm would vastly improve specificity.

If we fail to consider a simple addition of a relatively small number of accessible, rapid confirmatory tests, the population may lose confidence. Like all the testing problems, there are simple solutions. We should run with them. Rapid confirmatory tests is one of those.

But the confirmation cannot be lab based. It must be easy, accessible, immediate. The test should be considered a 2-step process. If test 1 is pos, then take test 2. If test 1 is neg, then don’t take test 2.
