Emergent SARS-CoV-2 Variants

Discrimination of Omicron from Delta and other variants

Surveillance Program

As the SARS-CoV-2 is continuously mutating and multiple SARS-CoV-2 variants are circulating globally, Siemens Healthineers has an active surveillance program in place. We continue to monitor the literature and the GISAID database to assess for new variants with the potential to affect the performance of the FTD SARS-CoV-2 Assay.1 

This update is based on in silico analysis from December 8, 2021 of 4,642,494 complete sequences for the ORF1ab target and 4,637,780 complete sequences for the N gene target of SARS-CoV-2 from the GISAID database (www.gisaid.org).

Variant Testing Workflow 

Omicron Positive Identification Reflex Testing Workflow

Eluates of positive SARS-CoV-2 samples are reflex-tested with Diagnovital L452R (RUO)4 and Diagnovital K417N (RUO)4 assays to help discriminate between Delta variant and Omicron variant suspected samples.

SARS-CoV-2 Mutation Profiling

Since the beginning of the pandemic, SARS-CoV-2 has continued to mutate, resulting in genetic variations in the population of circulating strains of the virus. A new variant of SARS-CoV-2 may have one or more mutations that differentiate it from the predominant virus variants already circulating in the population.

This table shows the major amino acid substitutions in the Spike protein for the variants of concern (VOC), variants of interest (VOI), and other variants under monitoring.
