The Immune System Holds the Key

SeptiCyte® technology can assess a patient’s immune response by quantifying and analyzing gene expression signatures from whole blood, providing actionable results in about an hour to guide the physician in optimizing patient management decisions.

The immune system holds the key to unlocking a better understanding, diagnosis and treatment of patients suspected of sepsis. The human immune system responds specifically to an invading pathogen and produces an abundant genetic signal that is reliably detected by SeptiCyte® technology. Using mathematical algorithms, a patient’s genetic material from the septic immune response is rapidly analyzed providing actionable clinical information in suspected sepsis cases.

Earlier, Faster and More Reliable Than Identification of Pathogens.

By testing whole blood directly, the assay is able to detect the response of the patient’s immune system to an infection earlier, faster and more accurately than methods that rely on identifying pathogens. SeptiCyte® host response results allow clinicians to better interpret positive and negative pathogen results, empowering them to swiftly differentiate systemic inflammatory response syndrome (SIRS) from sepsis in critically ill patients to be admitted to the ICU.

Clinical research results published in peer-reviewed medical journals have demonstrated the accuracy of SeptiCyte® technology in both adults and children suspected of sepsis.
