With Chai's easy-to-use analytical platform businesses can test common surface for Coronavirus and get results in under two hours.

Environmental monitoring surfaces is the proactive approach to Coronavirus management which complements human diagnostic testing and contact tracing. 

How Surface Testing for Coronavirus Works

Chai has taken every effort to make the testing process simple, so it can be performed by anyone, anywhere, in less than two hours. No lab or specialized scientists are required to run the environmental kit.

The key Coronavirus test reagents, known as oligonucleotides, have been freeze-dried in reaction tubes for simple use and stability. All other reagents are provided, with simple instructions. Automated software is baked into Chai's Open qPCR instrument to make running tests easy. The kit uses positive, negative, and internal amplification controls to ensure reliable results, which the instrument software automatically interprets.

Where and When to Surface Test For Coronavirus

  • Perform unobtrusive biosurveillance for COVID-19 exposure within facilities
  • Monitor efficacy of disinfection and decontamination efforts
  • Clear buildings post-exposure
  • Reassure workers, clients and public that an effective Coronavirus management program is in place
