PolyHeme, from Northfield Laboratories, is another type of artificial blood. At first glance, artificial blood seems like a good thing. It has a longer shelf life than human blood. Since the manufacturing process can include sterilization, it doesn’t carry the risk for disease transmission. Doctors can administer it to patients of any blood type.
