Our Mission

Our mission is to enable the first point of contact in the healthcare system to immediately identify sepsis and other medical conditions, and to facilitate the most appropriate treatment.


By bringing time-critical tests to the point of care, we aim to:

  • Facilitate faster diagnosis by reducing the time from infection to diagnosis
  • Reduce the time, distance, and cost barriers for people to get diagnosed
  • Identify unknown or underlying conditions earlier

For us, success means a faster path to disease diagnoses and treatment globally that will:

  • Make it easier to treat serious illnesses and reduce their long-term impact
  • Decrease patients’ time living with painful or life-threatening conditions
  • Reduced medical costs
  • Widespread accessibility to routine tests and screening
