Talis One™
Covid-19 Test System

Central lab quality SARS-CoV-2 molecular testing
for a variety of care settings—less than 30 minutes
from sample to results.

Because fast results should also be accurate

As SARS-CoV-2 continues to evolve, new variants may become more transmissible. As such reliable testing is one of the more effective ways to identify individuals who may need to quarantine and to prevent transmission of the disease.1,2

The Talis One™ COVID-19 Test System is a rapid point-of-care COVID-19 test that enables highly sensitive SARS-CoV-2 RNA detection from nasal mid-turbinate swabs in less than 30 minutes. With its dual-gene target design, test sensitivity and inclusivity of variants is optimized.3

Triage with confidence, without the wait

The easy to use sample-to-answer workflow and small instrument footprint bring all the benefits of molecular testing to a variety of care settings, maximizing the impact of testing on patient health and the containment of disease spread.

The Talis One COVID-19 Test System uses proprietary technology to deliver Nucleic Acid Amplification Test (NAAT) results quickly. Unlike other rapid point-of-care COVID-19 tests4 that may not be as sensitive, the Talis One COVID-19 Test System is able to achieve central lab quality detection of SARS-CoV-2 due to our patented on-cartridge sample purification step. With the on-cartridge sample extraction and purification and other proprietary technologies, the Talis One Covid-19 Test System achieves a limit of detection (LOD) of 500 copies/mL.5

  • Delivers lab-quality results in a variety of care settings including non-acute, CLIA-waived settings in educational facilities, workplaces, public health clinics, etc.
  • Targets SARS-CoV-2 N and ORF1ab genes for inclusivity of variants
  • Includes human beta actin as a sample processing control
  • Samples are added to a fully self-contained cartridge
  • Precision pipetting is not required
  • Sample extraction, purification, amplification, detection, and analysis is automated
  • Goes from sample to results in less than 30 minutes
  • Hands-on time less than 2 minutes
  • Reliable NAAT results are clearly displayed and actionable immediately upon completion of test

Access lab-quality testing at the point of care.
