End to end product

During the current pandemic, we have diverted resources and expertise into developing simple, low cost and scalable testing products for COVID-19.

The Chronomics test is one of the world’s first saliva-based tests for the identification of COVID-19 infection. This test uses the RT-PCR method and a protocol similar to the ones defined by the US Centre for Disease Control (CDC) and the World Health Organisation (WHO). It has been extensively validated globally for the detection of viral RNA from the virus that causes COVID-19, known as SARS-CoV-2.

Product Spec

Chronomics end-to-end product solution includes reagent and software modules to deliver on-site and at-home testing out the box.

  • End-to-end CE marked IVD.
  • Bespoke software to make logistics easy.
  • Efficient bead-based RNA extraction.
  • Compatible with open-source robotics.
  • RT and qPCR reactions performed in one step.
  • Multiplex qPCR assays for lower cost and higher throughput.
  • CDC- and WHO-based approach.
  • Limit of detection (LoD): 0.75 copies of viral RNA/µl
  • Specificity >99.99%
  • Sensitivity >97%
  • Result reporting and analytics modules included.

Chronomics now offers fully supported sample handling and processing workflows for saliva and other respiratory specimens. The CE marked end-to-end product contains the following components:

SaliVIR OME Collect kit
: This sampling kit contains a saliva collection device with all necessary components for the distribution and handling of Category B pathogens such as suspected positive COVID-19 samples.

SaliVIR Bead Xtract Viral RNA/DNA Kit: This extraction kit is designed for the rapid and reliable isolation of viral DNA or RNA from saliva or other respiratory specimens. The magnetic bead-based technology enables the purification of high-quality ribonucleic acid free from protein and other impurities required for downstream qRT-PCR. Fast, low cost and easily scaled up or down, the SaliVIR Bead Xtract Viral RNA/DNA Kit is ideally suited to COVID-19 testing.

SaliVIR COVID19 Rapid Multiplex qRT-PCR Kit
: This one step and multiplex qRT-PCR kit uses proven primer and probe sequences targeting two different genes from SARS-CoV-2 (assay N1 and assay E) and an internal human control (assay RP). The primer and probe sequences have been previously defined by the US Centre for Disease Control (CDC) and the World Health Organisation (WHO) and have been extensively validated for the detection of COVID-19. The kit is provided with both positive and negative controls

Chronomics has developed a suite of software modules to ensure that this end-to-end product can be set up and run rapidly and efficiently. SaliVIR COVID19 Sampling and Reporting modules are included as standard within the end-to-end product solution. SaliVIR COVID19 Analytics and Population modules are additional modules designed to support governments with population screening programs.
