How Does the QuantiVirus™ SARS-CoV-2 Test Kit Work?

The assay is a multiplex rRT-PCR assay consisting of one reaction with primers and probes for the viral targets (Orf1ab, N and E genes) and internal control in one tube thus with increased assay throughput and ease of use and other advantages as a multiplex assay.

The Orf1ab, N, and E genes of the SARS-CoV-2 genome are targeted in the rRT-PCR assay. Primers and TaqMan probes designed for conserved regions of the SARS- CoV-2 virus genome allow specific amplification and detection of the viral RNA from all strains of SARS-CoV-2 from respiratory specimens. The Human RNase P gene is used as Internal control to monitor viral RNA extraction efficiency and assess amplifiable RNA in the samples to be tested.

Product Configuration


Kit Components

High Throughput & Ease of Use


Detected Genes

Orf1ab, N and E genes


High Throughput

93 samples (96-well plate) or 381 samples (384-well plate) per run


Ease of Use

One sample in one qPCR reaction well (1 assay mix/per sample)

Turnaround Time is Less than 2 Hours from RNA Extraction to Results

Step 1

Extract RNA from patient sample and extraction control using Thermo Fisher PureLink viral RNA/DNA mini kit or Qiagen QIAamp® Viral RNA Mini Kit or equivalents

Step 2

Set up the assay reactions using primer/probe mixes and one-step RT-qPCR master mix. A positive (PC), NTC (NC) and extraction control (EC) must be included for every run

Step 3

Perform RT-qPCR using the Applied Biosystems™ QuantStudio 5, or 7500 Fast Dx, Bio-Rad CFX 384 or Roche LightCycler 480 II Real-Time PCR Instrument

Step 4

Data analysis 

Step 5

Review results interpretation for patient samples



Analytical Sensitivty

100 copies per mL of viral RNA 


Clinical Sensitivity
