Results from OIST antibody test In step one, which used one part of the spike protein – the receptor-binding-domain (RBD) – 63 OIST samples were above the threshold, indicating that their sera contained antibodies that recognized this antigen. All positives from step one were re-tested at various dilutions against the spike protein, but none of these were positive. The negative controls were serum collected before December 2019. The positive control was taken from a pool of samples that were PCR-positive earlier this year. The cluster case represents one of the first COVID-19 group infections on Okinawa.
