BY STEVE USDIN, WASHINGTON EDITOR | FEB 25, 2020 | 4:32 PM EST The Singapore Ministry of Health has used an antibody test developed by the Duke-NUS Medical School to determine the source of a COVID-19 cluster. The ministry reported that it is the first use anywhere of antibody-based testing for exposure to SARS-CoV-2, the virus that causes COVID-19.
The antibody test is important because it can be used to identify individuals who have been exposed to the virus and are asymptomatic or have recovered from the disease.
Antibody tests can be used, as in the Singapore case, to trace and isolate disease clusters.
Antibody tests could be used more broadly to determine how and where SARS-CoV-2 is spreading in communities.

That would be a great help. Leaps and bounds ahead of the CDC.
