Multiplex Detection of
SARS-CoV-2, Influenza A and Influenza B

This multiplex RT-qPCR assay detects SARS-CoV-2, Influenza A and Influenza B on three different channels, determining if the sample contains one, two, or all three of the viruses. The assay uses RNase P as the sample control gene on the fourth channel.

Two Protocols – Same Kit

Direct: No RNA Extraction (LDT), straight from VTM/UTM*

Extracted: Use CDC Recommended RNA Extraction

Targets
N1 SARS-CoV-2, M1
Influenza A, NS2
Influenza B and human
RNaseP genes

Samples

PERFORMANCE EVALUATION

Contrived Clinical Samples

LoD study for AzureSeq Plus, Direct Protocol

The inactivated virus was spiked into a negative swab sample plus saline, at 10 copies/uL, 5 copies/uL, and 2.5 copies/uL. Samples were heated at 95C for 5’, then 5uL of sample was added to a final reaction (total 20uL) containing AzureSeq Plus reagents. 20 replicates of each concentration was amplified using recommended cycling conditions (see below). The LOD for the Direct Method (no RNA purification) has been determined to be 10 copies/uL for N1 SARS-CoV-2, M1 Influenza A, and NS2 Influenza B on the BioRad CFX96 Touch Real-time Detection System at least 95% of the time using the AzureSeq Direct Plus RT-qPCR Respiratory Infection Kit with recommended cycling conditions.
