Is blood a commodity that can be bought and sold like any other commodity?

A World Health Organization (WHO) report says that Blood and blood products are a unique and precious national resource because they are obtainable only from individuals who donate blood or its components.. At question is whether one person should benefit at the expense of the health of another person. Accepting harm or injury to another, through allowing the donation of body parts or fluids, is one thing, but paying for those parts or fluids means assigning a price to these essentials of life. While blood is replenishable, most organs cannot be regenerated, and the fear is that the most economically vulnerable are the most likely to accept money for body parts or fluids, to the detriment of their health.
