Canadian team’s sepsis-testing device shows promise in fight against one of the world’s most common killers

In February, 2023, a Toronto man woke up feeling sick. Within hours, he was in the emergency room, where his lips and fingertips started turning blue. Blood samples were drawn and sent to the lab, and the patient was transferred to intensive care.By the end of the day, he was dead. He was only 22. “It was so fast,” says Claudia dos Santos, a physician-scientist with Unity Health Toronto’s St. Michael’s Hospital, who treated the patient.
