A lot of mistakes in this paragraph - all of this simply isn't true because of mixing of sensitivity/specificity + calc mistakes. For these types of tests, we assume high specificity, but lower sensitivity - but that doesn't lead to the results mentioned in this paragraph. 3/4pic.twitter.com/BuYppZFRH0

"Given how readily the SASR-CoV-2 spreads, “a misdiagnosis is worse than no diagnosis,”" I disagree with this - for the intended POC usage of RDTs, this is less of a concern. I'm very optimistic about RDTs - they won't be perfect, but they'll make a big difference 4/4

So I wonder, I think we care most about people with significant viral loads? As they might be a spreading risk, and I think these would be easiest to detect with such a test? Thanks!

Yup, I believe this to be the case as well - although we don't actually know if that truly is the case, I believe it is a very plausible hypothesis.

Do respiratory infections sometimes produce an IgA or IgM or salivary or cell-mediated immune response, without detectable IgG ? And can immunity nevertheless be conferred?

These might help get air travel going.

The problem is that only one lab can deliver an accurate test strip at this point in time.
