According to Katie McGuire, marketing and communications manager for the Greater Chesapeake and Potomac blood services region of the American Red Cross, giving blood is quick and simple. The 1995 graduate of The John Carroll School, Bel Air, said the actual process of giving blood lasts about 10 minutes, while the entire process takes just one hour. Before giving blood, donors should drink extra water and non-caffeinated, non-alchoholic beverages and eat plenty of iron-rich foods.
