What COVID tests mean and don’t mean
Two different tests, and what they interpret.
" RT-PCR tests can be designed to be highly sensitive to the presence of the original viral RNA in a clinical sample.
But a highly sensitive test risks poor specificity for actual infectious disease."
The "Rapid antigen tests are different. They measure viral protein.
They do so by reacting a clinical sample with one or two lab-created antibodies that are labeled with a measurable marker.
These antigen tests are often poorly specific, meaning they can show as positive in the absence of any actual viral protein or any COVID disease."
