According to articles posted by RSNA, 71% sensitivity for the SARS-CoV-2 RT-PCR Test. This is the test being doled out by various governments. I would venture to say that the CDC test is even less sensitive than in other countries given reports about serial testing. Each government appears to be using different RT-PCR tests with different primer sets. The SARS-CoV-2 test is highly specific, I would venture to guess around 98% or higher with the thresholds they are using. CT has very low specificity for COVID-19 vs other types of viral pneumonia, but high sensitivity for detecting viral pneumonia. Basically, no one should hang their hat on using one test either CT or RT-PCR.
