About Us - Hero

Karius sees a world where infectious disease is no longer a major threat to human health.

Our mission: We strive to deliver unprecedented insight to enable physicians to make rapid life-saving treatment decisions.

About Karius

Karius is a life sciences company focused on generating genomic insights for infectious diseases with a non-invasive Karius® Test that helps clinicians make rapid treatment decisions.  


We are a team of clinicians, molecular biologists, data scientists, software engineers, and commercial experts drawn together by a shared commitment to improve patient health.


By using genomics and AI to map a patient’s microbial landscape from a single blood draw, Karius moves closer to a vision of a world where infectious disease is no longer a major threat to human health.  The Karius laboratory is CLIA-certified and CAP-accredited to perform high-complexity clinical laboratory testing.

Karius CEO Mickey Kertesz

"Infectious diseases are a leading cause of global mortality and an enormous area of unmet need. The Karius Test allows clinicians to diagnose infections more rapidly and accurately, helping them to devise precise and effective treatment plans for patients with the objective of speeding their recovery times.
I’m excited for future applications of our technology to combat infectious diseases worldwide."
