If you’re a reasonably healthy individual and you meet certain criteria, you can get paid to donate blood plasma, which is a fluid that makes up about half of your blood.
Clinics, hospitals, and medical companies often need more of it to treat patients and develop medication, which is why there are several companies that will pay you to “donate” it.
How much you can make depends on a few factors, including how often you donate. Many clinics will pay you large sums the first few times you donate (e.g., close to $100 for your initial few visits) and then lower their rates the more often you do so.
Most visits take around 90 minutes, although the first time you go, you’ll have to undergo a health screening, which may stretch the process to around 2 hours. You can usually donate twice per week (although most people don’t do it that frequently).
