Lots of questions about the role of serologic testing for #COVID19 over the past few days.

So, my $0.02:

1. We do not diagnose other respiratory infections w/ serology...#SARSCoV2 is no different. 2. Initial studies from China suggest seroconversion occurs in most pts around Day 11 (preprint below).

What this means is that serology is:

✔️#NotHelpful for Dx of acute/symptomatic infection.

✔️#DefinitelNotHelpful at the POC! 😱🤯
