Canadian scientists have developed a blood test and portable device that can determine the onset of sepsis faster and more accurately than existing methods. Examining blood samples from more than 3,000 hospital patients with suspected sepsis, researchers from UBC and Sepset, a UBC spin-off biotechnology company, used machine learning to identify a six-gene expression signature “Sepset” that predicted sepsis nine times out of 10, and well before a formal diagnosis. The National Research Council of Canada developed a portable device. PowerBlade. that uses a drop of blood and an automated sequence of steps to efficiently detect sepsis. Tested with 30 patients, the device was 92% accurate in identifying patients at high risk of sepsis and 89% accurate in ruling out those not at risk, delivering results in under three hours.
