Goldsite Statement on Omicron Variants


Regarding SARS-COV-2 Antigen Kit (Colloidal Gold), The Ability to detect the new SARS-CoV-2 variants


With the pandemic 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 (shown in table below) 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 Antigen Kit (Colloidal Gold) performs the same (i.e. no impact) when detecting the SARS-CoV-2 variants including but not limited to the following variants.
