This is a misprint. They meant to say 0.99 or 99%, not .99%
That means it's very reliable that any positive signal originates from covid19 antibodies, instead of from something else.
That does not mean that it's 99% accurate with regards to sensitivity.

This would mean the antibody test alone cannot tell the full extent of community spread.
