A blood test that can detect sepsis in five minutes could save thousands of lives.The revolutionary test has just been approved in Europe and could be used in NHS hospitals next year to prevent deaths. Sepsis is a life-threatening condition that occurs when the body’s immune system over-reacts to an infection and starts attacking its own tissues and organs. This can be triggered by anything from cuts and bites to urinary or chest infections. About 150,000 people develop sepsis in the UK every year, with 44,000 deaths. Many deaths could be avoided with greater awareness of symptoms and faster treatment.
