Credit card-sized device tests for heart disease using less than a drop of blood

Endothelial progenitor cells can become Endothelial cells (pictured),
which make up the lining of blood vessels. 

A new credit-card sized device could provide a way to test people for heart disease using a pinprick of blood. Developed by a team of researchers from Harvard and Northeastern universities in Boston the device can measure and collect a type of cells, called endothelial progenitor cells, using just 200 microliters of blood.

The depletion or ageing of these bone-marrow derived endothelial progenitor cells is a risk factor for vascular disease, as they can enter the bloodstream and go to areas of blood vessel injury to help repair damage…
