Accuracy of 2 Rapid Antigen Tests During 3 Phases of SARS-CoV-2 Variants.

ABSTRACT:

Importance

Variants of SARS-CoV-2 have sequence variations in the viral genome that may alter the accuracy of rapid diagnostic tests.

Objective

To assess the analytical and clinical accuracy of 2 rapid diagnostic tests for detecting SARS-CoV-2 during 3 phases of variants.

Design, setting, and participants

This diagnostic study included participants aged 18 years or older who reported onset of COVID-19-like symptoms within the prior 5 days and were tested at multiple COVID-19 testing locations in King County, Washington, from February 17, 2021, to January 11, 2022, during 3 distinct phases of SARS-CoV-2 infection (pre-Delta, Delta, and Omicron).

Interventions

Two anterior nasal swab specimens were collected from each participant-1 for onsite testing by the SCoV-
