Countries already on it or starting: Germany, Netherlands, UK, Singapore, South Korea, China
Country with no plan: US

There are many uncertainties w/ Ab testing:
—Do high levels of IgG protect from reinfection; how long do they persist, do they indicate an individual is incapable of spreading?
—The >20 tests vary w/r to methods, sensitivity, specificity, validation. Data are not transparent 2/x

The scalable tests (we need, massive, cheap quick) can be done in minutes via fingerstick.
Many resemble https://www.biopanda.co.uk  test (according to @TheEconomist).
The one I did last week was far more comprehensive but may not well suited for mass use

The @CellexInc fingerstick #COVID19 antibody test, with 15-minute turnaround, cleared yesterday via @US_FDA, the 1st of many, and perspective about what it shows (and doesn't) https://www.nytimes.com/2020/04/02/health/coronavirus-antibody-test.html by @apoorva_nyc

Terrific to see that @COVID19Tracking is curating all the info on antibody/serology diagnostics @hackingdata @airtable
