A Rapid, Multiplex Dual Reporter IgG and IgM SARS-CoV-2 Neutralization Assay for a Multiplexed Bead-Based Flow Analysis System
Published on: April 6, 2021
Background:
SARS-CoV-2 rapid antigen test can supplement the nucleic acid amplification method.
Methods:
We calculated the sensitivity and specificity of the GenBody COVID-19 antigen assay using 155 nasopharyngeal specimens.
Results:
The sensitivity in samples with their respective cycle thresholds varied from 33.3% to 100%; the sensitivity of the antigen assay was inferior to that of the gold standard polymerase chain reaction test.
Conclusions:
Considering the relatively fast speed of the antigen test and high sensitivity at a low cycle threshold value indicating a high viral load, the GenBody COVID-19 antigen test can be an easy and quick measure for detecting SARS-CoV-2 in individuals with high viral loads.
