Cavidi FAQ

Most frequent questions and answers​

No. Our goal is to create tests that are universally accessible to both developed and developing nations alike. Within that mandate, we must address the fact that three quarters of the world’s population live in resource-limited settings.

Many medical tests can only be run in highly advanced medical facilities. Cavidi’s vision is a world where proper medical tests are accessible to anyone who needs them. So we strive to produce state-of-the-art tests with a minimal resource footprint. This approach makes Cavidi tests globally applicable but particularly attractive in settings where resources are limited.

At Cavidi we try to develop test solutions that adhere to our ACCESS policy:

  • Affordable in the context of resource-limited settings
  • Clinically relevant to both the diseases and measurement parameters needed
  • Comparable to similar tests used in developed nations with regard to accuracy and reliability
  • Easy to run and read in the field
  • Swifter at showing results
  • Suited to the infrastructure-limitations of resource-limited settings
