Beautiful paper comparing SARS-CoV-2 antibody assays:
custom ELISA assay vs 9 lateral flow assays

Key takeaways:
1. ELISA can be highly specific (100% negative call in 50 pre-pandemic samples)
2. LF assays seem not ready for prime time

Table of key results.

Unfortunate: authors don't specify manufacturer names for the lateral flow assays

Are you confused by all the jargon around antibody tests?

This figure explains things nicely

Finally, nice figure on the time dynamics of the development of IgM and IgG antibodies by ELISA in 40 COVID-19 patients
