Microfluidic Assay to Diagnose Sepsis (IMAGE) Massachusetts General Hospital Caption After a drop of blood is placed into the central chamber of this microfluidic device, neutrophils can enter the mazes of channels on each side, while red blood cells and other components are retained in the chamber. Patterns of neutrophil migration within the channels can distinguish between patients with and without sepsis.
