Rapid emergence of SARS-CoV-2 Omicron variant is associated with an infection advantage over Delta in vaccinated persons, Chaguza et al
Validation of spike gene target failure (SGTF) as proxy for Omicron (BA.1) infection. We compared results of our RUO RT-qPCR assay with sequencing results to show that SGTF is an adequate proxy for detection of Omicron (BA.1) in our study population. We sequenced a subset of samples collected from November 22nd to December 27th. Our N1 threshold was set at Ct ≤30.
