in vitro diagnostic medical devices

With the outbreak of COVID-19, multiple SARS-CoV-2 virus variants have emerged, including B.1.1.7 lineage (Alpha), B.1.351 lineage (Beta), P.1 lineage 

(Gamma), B.1.617.2 lineage (Delta), B.1.1.529 (Omicron), etc.

Most of the mutations in these variants occur in the viral surface proteins (e.g. Spike  proteins), while few mutations occur in the nucleocapsid (N) because the N protein is 

essential for virus survival and is too conserved to change.

SARS-CoV-2 Antigen Kit (Colloidal Gold), manufactured by Goldsite Diagnostics Inc. is intended to detect the N protein in human nasal swab specimens. Both the two antibodies used on the test kit target the viral nucleocapsid (N) protein.

Based on the comparison analysis between the target epitopes and the mutation sites and the preliminary testing results, we hereby declared that SARS-CoV-2
