Portable Device Samples Blood without Needles

Apr-05-18 A device that lets chemotherapy patients monitor their white blood cell levels from home could help prevent dangerous infections.

Developed by a team from MIT, the prototype portable device relies on a microscope that emits a blue light able to penetrate just below the skin beneath the fingernail. The light is then reflected back to a camera to deliver an image that is analyzed by an algorithm to determine if the white blood cells are below a safe level. The patient can monitor their levels from home on a daily basis, offering an early alert if preventative treatments are required.
