Conclusion
COVID-19 antibody serology test helps to supplement the diagnosis of
COVID-19 infection and assess the adaptive immunological response of
healthcare workers to the infection. Although having a diagnostic test
is prudent, our survey showed the utility of a proper history taking
procedure as a first-line screening to risk stratify HCW for the
serology tests, especially when resources are limited. The established
relationship between clinical or epidemiological factors to the IgG
status underlines the importance of HCW to observe the standard hygiene
precaution and social distancing to avoid potential community or
nosocomial transmission. Periodic antibody surveillance of HCW during or
at the end of the pandemic with careful cost assessment may be
beneficial.
