Really not good to combine them at all. Not sure what the CDC is thinking... Or perhaps they don’t have much say in it.

The virus test is the gold standard and tells you if you have the virus right now; if you're sick but the test is negative then something other than COVID-19 is making you ill. The less accurate antibody test tells you if you've ever been exposed to the virus and a positive result may mean you are immune from the virus. One test looks ahead the other looks behind.

And states have been using these very questionable statistics to decide when it is safe to reopen!
