The U.S. is among only a handful of countries that allow donors to receive financial compensation for giving their plasma, the liquid part of blood. Donors here can receive anywhere from $30 to upwards of $100 per visit, and are permitted to donate plasma as frequently as twice a week, another rarity around the world. Regular donors can make hundreds of dollars a month.
