Amazing - Antibody serology #COVID19 testing in SG! “PCR will not work if patient recovered, body’s immune system has cleared virus. However, immune system produces antibodies in response to infection- virus specific antibodies stay w/ recovered patient”

2) Why is this important? antibody testing can better capture history of infection than a direct PCR molecular test of the virus. “the team proved that the two suspect Cases 83 and 91 were indeed infected w/ #COVID19 in late Jan, as they had very high levels of virus-specific...”
3) ...”antibodies in their blood. This result was a significant piece of evidence which confirmed the links between the church clusters and the two Wuhan travellers.” ==> basically antibody serology testing allowed the epidemiologist to link the clusters with Wuhan travelers.
4) I want to be clear - antibodies are body’s own immune system tools tools to recognize infection and recruit help to fight it. Antibodies do not cause any re-infection. They are just a signal the virus has been there previously (and now have antibodies to fight it next time)
