Altered movement of white blood cells may predict sepsis in patients with major burns

Researchers at Massachusetts General Hospital have identified a potential biomarker for sepsis in patients with major burns. By analyzing the movement of white blood cells called neutrophils, they found that changes in their motility patterns may predict the development of sepsis, which is a leading cause of death among burn patients.
