The payment for sperm donation varies across clinics or sperm banks. On the average, if you are accepted as a donor you can be paid between $35 and $100 per specimen. You can earn $1,000 to $1,500+ in a month based on factors like donation center, location, age and health.

The amount you will make for selling plasma varies depending on a number of factors, but plasma donation centers generally offer between $30 and $60 per donation session.

Community Blood Centers’ average is $310. But depending on the market, one unit can be worth a whole lot more. For example, the red blood cells can go for $229, platelets for $300 and plasma for $40 – nearly $570 in all.

To this cost was added an estimate of costs incurred by hospitals for handling, testing, and administering blood. Across study sites, the average hospital cost per unit transfused was $155 and the average charge to the patient was $219.

A pint of blood in America sells to hospitals for $180 to $300, depending on the market, and expired blood often is sold to research laboratories, said Ben Bowman, chief executive of General Blood, the blood broker engaged in a legal tussle with Oklahoma City-based OBI.

DONATIONS ARE VITAL AB- is only found in less than 1% of the population, making it the most rare and highly in-demand blood type. AB is the most desirable blood type for platelet and plasma donations.

Only about 3 percent of the U.S. population is AB+, making AB+ blood donors all the more valuable. Although people with AB+ blood can receive from any blood type, it is always preferred to receive blood from a person with the same blood type.

Same for B group people. O blood type people inherited two O genes. People with AB blood inherited an A gene from one parent and a B gene from the other. Based on the underlying number of people in the A and B blood types, the odds of that particular combination happening are simply lower than any other possibility.
