Avoid diagnostic wrong turns and blind alleys.

Karius is a life sciences company focused on saving lives. We advance diagnostic science and technology in order to deliver breakthroughs and upgrade the standard of care in the fight against infectious disease.

The Karius Test™ is a liquid biopsy for infectious diseases that can free clinicians from the diagnostic maze so they can return patients back to health quickly and safely.

From a single blood sample, the Karius Test can non-invasively and rapidly detect over 1000 pathogens causing both deep-seated and bloodstream infections. The Karius Test helps clinicians avoid invasive, low-yield, and sequential diagnostic tests that can delay treatment for the most vulnerable hospitalized patients.
