Umbilical cord blood analysis
Seventy-eight umbilical cord bloods, from mother who participated in
this study, were assessed for the presence of SARS-CoV-2 antibodies. Of
these, five mothers (3 in the symptomatic cohort and 2 in the
asymptomatic cohort) delivered during this study period. All five
umbilical cord bloods demonstrated IgG antibodies to SARS-CoV-2 (Table
2). The median antibody index was 4.88 (Roche) and 2.33 using the
Alinity platform. Predictably, all of the cord bloods were negative for
the presence of IgM antibodies
