Plasma is the yellow liquid part of the blood the carries water and nutrients to other cells in your body. There is a healthy demand for plasma, which can be used to produce therapies that can help people with rare diseases.
What It's Worth: Though many donate plasma for free, there are some places which will give you money in exchange for yours. Bloodbanker.com listed BioLife in Chicago as a purchaser of plasma, which will pay from $15 to $50 for your first donation, and $15 to $30 for subsequent donations.
Wait a Minute: You can opt to help someone out out of your own goodwill by donating your plasma for free. If you donate too frequently, you may also have lower levels of antibodies and hemoglobin. However, these health issues can be dealt with if you take a break between donations and take supplements.
Donating plasma is also different from donating blood in that it can take about two to three hours for your first time.
