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"> 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

Terrific to see that @COVID19Tracking is curating all the info on antibody/serology diagnostics https://abs.twimg.com/emoji/v2/... draggable="false" alt="🙏" title="Folded hands" aria-label="Emoji: Folded hands"> @hackingdata @airtable
