For Patients

At Karius, we envision a world where every patient gets a clearn and timely diagnosis.

Who We Are

At Karius, we are dedicated to transforming infectious disease diagnostics for vulnerable, immunocompromised patients. Karius is a medical company that helps doctors find infections faster using a simple blood test with advanced technology.

What We Do

For people with weakened immune systems undergoing cancer treatment or who have had a transplant, infections can be serious. We help your doctors find the answers they need, so you can focus on feeling better. Our test helps doctors quickly learn what organisms such as bacteria, viruses, parasites, or fungi may be causing life-threatening infections in hospitalized patients.

Our Product

Helping You and Your Doctor Find the Cause of Infection Quickly

Traditional tests may not always find the cause, leaving doctors without the answers they need. Karius Spectrum is an infectious disease test that can detect over a thousand bacteria, fungi, parasites, and viruses from a single blood draw, helping your care team uncover hidden infections that may help guide your treatment.
