So if you see a paper that shows very low sensitivity, ask:
"Are they comparing rapid antigen tests to "anytime" PCR RNA positivity? (Especially studies asking about sensitivity among asymptomatics)
2/x
Anyone seriously commenting on or writing scientific papers about rapid tests vs PCR should include impact of speed & frequency

NOT just lowest limit of detection
The latter is the least important for public health
Access frequency & speed are each MUCH more important metrics
